(7x8)-6x2+7

56-6x^2+7
63-6x^2

To simplify the expression (7x8) - 6x2 + 7, you need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right).

Let's break it down step by step:

Step 1: Start by evaluating the multiplication from left to right.

- (7x8) = 56
- (6x2) = 12

The expression becomes:
56 - 12 + 7

Step 2: Now perform the subtraction and addition from left to right.

56 - 12 = 44
44 + 7 = 51

Therefore, the simplified expression (7x8) - 6x2 + 7 is equal to 51.
