Hello! I would love to help you out with this question!
So, To simplify the expression -12+(-66)+48, we need to perform the addition and subtraction operations in order from left to right. Let's break it down step by step:
First, let's simplify -12 + (-66). To add two negative numbers, we add their absolute values and keep the negative sign. So, |-12| + |-66| = 12 + 66 = 78. Since both numbers were negative, the sum will also be negative. Therefore, -12 + (-66) = -78.
Now, we can substitute -78 into the original expression: -78 + 48.
Next, let's perform the addition operation: -78 + 48 = -30.
Therefore, the simplified expression -12+(-66)+48 is equal to -30.
Hopefully, this helped you understand!
