Question

What should be done so that the expression will have a value of 10? 12 - 2 + 22 ÷ 8

Answer 1

So, to make the expression have a value of 10, we need to group the first two terms together using parentheses and then add the result to the third term. The resulting expression is (12 - 2) + (22 ÷ 8) = 10 + (2.75) = 12.75.

Answer 2

`12 - 2 + 22 ÷ 8 \\ replace \:( 12 - 2) \: with \: 10 \\ = 10 + 22 / 8 \\ = 10 + 2.75 \\ = 12.75`
