To evaluate this expression, we follow the order of operations, which is known as PEMDAS.
PEMDAS stands for:
1. Parentheses
2. Exponents (i.e. powers and square roots)
3. Multiplication and Division (from left to right)
4. Addition and Subtraction (from left to right)
Using PEMDAS, we first simplify within parentheses:
70 - 7 * (-6) = 70 - 7 * 6
Next, we perform the multiplication:
70 - 7 * 6 = 70 - 42
Finally, we subtract:
70 - 42 = 28
Therefore, 70 - 7 * (-6) equals 28.
