Let the number you are looking for be x. Then 9 + x = 10 + 10. x is 11.
'Sum' is pretty much a synonym for add, and 5+5 or 5 plus 5 is 10.
4 plus 10 plus 16 plus 70 equals 100. To find the sum of this series, simply add all the numbers together.
the sum of 10 + 10 = 20
The sum of 10 plus 8 is 18.
4 plus 10 = 14
'Sum' is pretty much a synonym for add, and 5+5 or 5 plus 5 is 10.
4 plus 10 plus 16 plus 70 equals 100. To find the sum of this series, simply add all the numbers together.
the sum of 10 + 10 = 20
The sum of 10 plus 8 is 18.
the sum of 80 + 20 + 90 + 10 = 200
The sum answer = 3440
4 plus 10 = 14
-1+1+2+3+5= 10 First, you move 1 left of "0", which is -1. Then, you move 1 digit to the right, which puts you back at "0". Add 2, add 3, and add 5. The sum is 10.
1/5 plus 1/2 is the same as 2/10 plus 5/10 = 7/10
Add the tenths together to get 13/10... This gives you 1 and 3/10... Now - add in the whole numbers from the original sum, and you get 4 and 3./10
the sum of 1 plus 9 is 10 because 1+9
The answer is 13. Simply add the numbers together arithmetically as you would for the problem two plus two. To check your work, a calculator is the best option.
