Evaluate: (−7)+8x8
____
8
The expression (-7) + 8 * 8 / 8 can be further simplified as follows:
From the order of operations (parentheses, exponents, multiplication/division - left to right, addition/subtraction - left to right), we start with the division:
8 * 8 = 64
Then we do the addition:
(-7) + 64 = 57
Finally, we divide the result by 8:
57 / 8 = 7.125
Therefore, the evaluated expression is 7.125.
To evaluate the expression (−7) + 8 × 8 ÷ 8, we follow the order of operations, which is also known as PEMDAS (parentheses, exponents, multiplication/division from left to right, and addition/subtraction from left to right).
Given expression: (−7) + 8 × 8 ÷ 8
Step 1: Start with multiplication and division.
8 × 8 = 64
64 ÷ 8 = 8
Step 2: Perform addition and subtraction.
(−7) + 8 = 1
Step 3: Put the values together.
1 ÷ 8 = 1/8
Therefore, the evaluation of the expression (−7) + 8 × 8 ÷ 8 is 1/8.
