Strictly speaking, it is ADD.

The word 'sum' is used colloquially for any simple arithmetical calculation, but in mathematics a 'sum' is properly the result of adding two or more numbers.

### How do you work out sums?

Step by step and following the mathematical instructions as given by the expression.

### How do you work out the sum of a triangle?

A triangle has no sum. There can be a sum of the measures of two or more angles, or the lengths of two or more sides, for example.

### How do you work out the sum 48-32 plus 26-18?

Without parentheses, the operations proceed in order, left to right. The answer is 24.

### How do you work out minus sums what is the sum of minus 3 take away plus 5?

It is sometimes helpful to think of "minus" as a debt. So +3 means you have 3, while minus 3 i.e. -3 means you have a debt of 3. Then you have the business of adding and subtracting. Minus three takeaway plus five: Means you are already in debt for 3 and taking away 5 means you are now down to minus 8. Example -3 + +5 is written -3+5 which is down 3, up… Read More

### How do you work out the sum of the exterior angles?

exterior angles always add up to 360 degrees, but 'exterior angle' refers to the angle that is made when you continue one of the lines. eg a square has 4 sides, make one of them longer so you end up with a thing like below, and the exterior angle is the one that's not 180 degrees. if you don't get it its quite hard to explain without a proper diagram, so Google pictures exterior angles… Read More

### How do you work out the sum of exterior angles for a pentagon?

all regular polygons (such as a pentagon) have the sum of their exterior angles = 360 degrees

### How do you work out the sum of exterior angles for a square?

Each angle of a square is 90 degrees. Subtract that from 360 to get...270 degrees for each of the four exterior angles. Multiply that by 4 to get a total of....1080. I think that's how it works..someone correct me if I'm wrong.

### What is a Riemann Sum used to define?

In mathematics, a Riemann sum is a summation of a large number of small partitions of a region. It may be used to define the integration operation. The method was named after German mathematician Bernhard Riemann.

### How do you work out the sum 72 divided by 1.5?

Easy I am 9 years old and i can work that out. you put 1.5 then one line up, then a line across. in between those lines you put 72 and then you work it out and you'll find its 48.

### How do you work out the angle sum of any polygon?

The sum of the interior angles (the angles of a polygon is equal to the 180*(n-2), where n is the number of sides. For example, if a polygon has 5 sides the sum of the angles is 180*(5-2), which is 540 degrees. The sum of the exterior angles (the angles on the outside of the polygon made by extending a side and measuring the angle between the extension and the nearest side) is always equal… Read More

### How do you work this sum out -643.49 plus 154.77?

-643.49 + 154.77 = -488.72 Just like normal addition

### How do you work out the sum if you add 6.49 to 3.4 times a number and you get 97.61 what is the number?

1. you add the two numbers. 2. then you divide the total by that number. So: let x represent the missing number 1. 6.49 + 3.4= 9.89 2. 97.61/9.89= x

### How do you work out what 36 as a fraction of 60 and more sums like this how do you work them out?

36 as a fraction of 60 is written as 36/60. That can be reduced to 3/5 by dividing both the numerator and the denominator by their GCF, which is 12. 3/5 can be expressed as a decimal (0.6) by dividing the denominator into the numerator and 0.6 can be expressed as a percentage by multiplying it by 100 (60%) 36 is 60 percent of 60.

### How do you work out the sum of the first 100 odd numbers?

This is very easy. Simply square the number: 100 squared (100 x 100) = 10,000. So, the sum of the first 100 odd numbers is 10,000.

### What is the sum total of a person's surroundings?

A person's environment means everything around them. or you can say its the enviroment

### How would you work this sum out a x a x a .would it be 3a or to the power of 3?

it will be a cube or a to the power of 3.

### What is the mathematic definition for sum?

The total amount resulting from the addition of two or more numbers, amounts, or items

### How do you work out how many sides a polygon has from the sum of the interior angles?

Sum of interior angle of n-sided polygon always = (2n - 4) right angles or 180n - 360 degrees.n therefore = (known total + 360)/180eg if the known total is 540 degrees, n = (540 + 360)/180 ie 5.

### What sum do you do to make 27 out of 1234?

Assuming the order of the numbers is not important, then ((4 x 2) + 1) x 3 = 27.

### How is a benchmark used to estimate fractions sums?

A benchmark is an easy to work with number. you round fractions to the nearest benchmark and it will be very easy to add. i use 1/4, 1/2, 3/4, 1, 1 1/4, 1 1/2, 1 3/4, 2, 2 1/4, and so on as benchmarks.

### How do you produce the sum of a column by using the auto sum function?

Assuming you're using Microsoft Excel, select the entire column by clicking and dragging with the mouse, then press the AutoSum button (looks like Î£).

### How many times must you throw 2 dice to be sure you get the same sum at least twice Working out please?

1 out of 6* * * * *Total rubbish.There are 11 possible sums - the numbers 2 to 12. So if you throw the dice 12 times, the first 11 can be different but the 12th must be a repeat.

1.918 is the answer Partial Sums:1.055+.863-----------1.918

### Are there any uses for setting out bracket sums?

Yes. The default order of evaluating expressions is BODMAS/PEMDAS. To change that order, parts of the expression need to be put in brackets (parentheses). Yes.

### What is the sum of 1999 and 2014 worked out in two different ways entirely In Roman numerals showing work with explanations?

Because of changes made to the real rules regarding the governance of the original Roman numeral system made during the Middle Ages nowadays 1999 and 2014 when converted into Roman numerals are officially MCMXCIX and MMXIV which seems rather strange because they don't quite easily lend themselves to the 4 basic mathematical operations of arithmetic one of which is addition.But there exist historical evidence to show that the ancient Romans would have probably added together… Read More

### How can you determine whether a sum of numbers is even or odd with out building a tile model or computing the sum?

You can just add the last digit of each number. Whenever you get a two-digit number, you can discard all digits except the last one.Another alternative is to count how many odd numbers there are - once again, you only need to consider the last digit. If the number of odd numbers is even, the sum is even; otherwise it is odd. (You can ignore even numbers for this calculation.)
