Question 897976: so, i don't actually know if this catagory is correct but I believe it is. The question is "What is a quick way to see that the value of the sum 53 + 18 + 47 + 82 is 200?" and I figured just add them together but that seems like not the right answer. Thanks again

"What is a quick way to see that the value of the sum 53 + 18 + 47 + 82 is 200?"
:
They want you to pick out a pair of numbers in the group that will add up a multiple of 10. Multiples of 10 are easy to add together in your head.

Look at the group of numbers, you should recognize the 53 and 47 = 100
Then you should recognize that 18 and 82 also = 100, hence the sum is 200
