What is the word you use to work out a sum?
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.
it is calculator i think
addition.. (+) operand, caculator..
Step by step and following the mathematical instructions as given by the expression.
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.
You work it out on paper or just use a calculator
Without parentheses, the operations proceed in order, left to right. The answer is 24.
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
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
all regular polygons (such as a pentagon) have the sum of their exterior angles = 360 degrees
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.
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.
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.
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
15/2.5 = 6 is the same as 150/25 = 6
-643.49 + 154.77 = -488.72 Just like normal addition
217/6.2 = 35 which is the same as 2170/62 = 35
Sorry, use what? "Addends" are what you add together to get a sum.
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
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.
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.
It means add it up or total
three-fourths of the sum of q and 5
A person's environment means everything around them. or you can say its the enviroment
it will be a cube or a to the power of 3.
The total amount resulting from the addition of two or more numbers, amounts, or items
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.
use a calculator.....
Assuming the order of the numbers is not important, then ((4 x 2) + 1) x 3 = 27.
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.
Assuming you're using Microsoft Excel, select the entire column by clicking and dragging with the mouse, then press the AutoSum button (looks like Σ).
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
An equal sign

0. Because 456 + 0 = 456. and the digit 4 is used twice in the sum.
1 + 2 + 3 + 4 + 9 + 10 + 15 + 16 - 5 - 6 - 7 - 8 = 34
The sum of any one number, such as 832, is itself. Simple!
It is not possible to answer this question without information on whether the terms are of an arithmetic or geometric (or other) progression, and what the starting term is.
1) Add up all values 2) Divide by the number of values
(number of sides-2)*180 = sum of interior degrees

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
5 + 5 - 5 - 5 + 5 + 5 = 10 (5 + 5) x 5/5 x 5/5 = 10
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.)
