Answer:

7+(7–7) ÷(7+7•7)= 7

Step-by-step explanation:

The difference 7 - 7 provides an opportunity to zero out everything to its right. That's what we've done in this version:

7 +(7 -7) ÷ (7 +7×7) = 7 . . . our version of the equation

7 +0 ÷ (7 +49) = 7 . . . . . multiplication inside parentheses first

7 +0 ÷ 56 = 7 . . . . . . . . parentheses first

7 +0 = 7 . . . . . . . . . . . . division before addition
