How can you rewrite \(72 + (8 + 19)\) to make it easier to add?

Asked by solymar4ever12

Answer (3)

First add up the numbers in the parentheses. 8+19, take that answer plus 71. When doing large questions like this I prefer to do things like this. 71 + 27 _____
Take the ones column, adding it up, 1 plus 7, then put that 8 down here like this: 71 + 27 _____
8 Then add add the other two, 7 plus 2 is 9. So you would end up with something like this: 71 + 27 _____
98

To make 72+(8+19) easier to add, use the** associative property** to first add the numbers inside the parentheses, resulting in 72+27. Then add those two terms to get the sum, which is 99. ;

To simplify 72 + ( 8 + 19 ) , we first compute 8 + 19 to get 27 , leading to 72 + 27 = 99 . This uses the associative property of addition for easier calculation. The total is 99 .
