3+6*5+4:2-7 using the same expression, add parentheses so that the value of the expression is 38

3+6 * (5+4:2) - 7

Step-by-step explanation:

To solve the expression use order of operations.

Right now the expression solves to:

3+6*5+4:2-7 6 * 5 = 30

3 + 30 + 4:2-7 4 : 2 = 2

3 + 30 + 2 - 7 Add and subtract left to right.

33 + 2 - 7

35 - 7

28

To make it solve to 38, add parenthesis:

3+6 * (5+4:2) - 7 (5+4:2) = 7

3+6 * (7) - 7 6*7 = 42

3 + 42 - 7 Add and subtract from left to right

45 - 7

38
