Why is it useful for me to know the absolute value of a number?
The absolute value of a number is the distance to zero. When adding which ever number has the greater absolute value will determine the sign of the answer.
How do iPhone the UK from Spain?
Dial the number by adding 0044 to the beginning of the phone number, then do NOT include the first 0 of the areacode.For example:A phone number with the area code 0870 becomes 0044 870.
What does counting numbers mean in math?
It means the numbers you use when you count things. They are the positive integers, beginning with ' 1 ', and finding each number on the list by adding 1 to the previous number.
Adding a force acting in the opposite direction is the same as adding a n number and a n Number?
it is the same as adding a negative number to a positive number
What is adding mixed number?
a mixed number is a whole number with a fraction, ie. 2 3/4 Adding mixed numbers involves adding the whole numbers, then adding the fractions, then reducing the fraction and if it is improper, changing it to a whole number with a fraction and adding that whole number to the other whole number answer.
What is the distance between -5.6 and 3.9 on a number line?
9.5Since one number is negative and one positive we can solve by adding thedistance (absolute value) from each number to zero:3.9 + l-5.6l = 9.5
Why do two even numbers always equal an even number?
On a number line, adding an even number to another number (or zero) results in an even displacement, which must end in the same type of number as the original. If the beginning number is odd, adding an even number produces an odd sum. If the beginning number is even, adding an even number produces an even number. A corollary is that: Adding two like numbers produces an even number. Adding two unlike numbers produces an odd number. ---------------------------------- Algebraically: let x be an even number, Then y = 2x for some value of x Two even numbers would be 2m and 2n Adding them gives: 2m + 2n = 2(m + n) = 2p where p = m + n; 2p is of the form y = 2x, so 2p is an even number. Thus adding two even numbers results in an even number. Similarly for odd numbers: If y = 2x is an even number then z = y + 1 = 2x +1 is an odd number. Two odd numbers would be 2m+1 and 2n+1 Adding them gives: 2m+1 + 2n + 1 = 2m + 2n + 2 = 2(m + n + 1) = 2p where p = m + n + 1 Thus adding two odd numbers results in an even number. Similarly for one even and one odd number. An even number would be 2m and an odd number would be 2n+1 Adding them gives: 2m + 2n + 1 = 2(m + n) + 1 = 2p + 1 where p = m + n Thus adding an even number and an odd number results in an odd number.
How do you call somebody in the Bahamas?
you can someone in the Bahamas from another address by entering 1-242 and then adding the local 7 digit number.
Is 6.070 equal to 6.07?
Yes. Adding zeroes to the beginning of a number before the decimal place, or to the end of a number after the decimal place, doesn't change the number. So: 1.2 = 01.2 1.2 = 1.20 1.2 ≠ 10.2 1.2 ≠ 1.02
Does adding 0 change a number?
Adding zero to a number will give you the same number. Example: 5 + 0 = 0
How is adding on number line different from subtracting on a number line?
When subtracting, the number moves to the left (negative direction). When adding, the number moves to the right (positive direction).
Does the number line have a beginning?
No. However, it does have to have a beginning number. beside the beginning number, on the actual line, you would put an arrow on the end of it, because numbers are infinite in both directions.
