Chapter 1: Problem 63

Find each sum. $$-20+[-|15+(-25)|]$$

Short Answer

Expert verified
The solution to the expression \(-20+[-|15+(-25)|]\) is \(-30\).

Step by step solution

01

Evaluate the expression within the bars of the absolute value

First, add the numbers inside the absolute value bars. The operation within the bars is \(15+(-25)\), which simplifies to \(-10\).
02

Simplify the resulting Absolute Value

Next, evaluate the absolute value of \(-10\), which is \(10\). The absolute value of a number is always positive or zero. Hence, the simplification becomes \(-20 + [-10]\).
03

Evaluate the negative sign outside the square brackets

Observe that there is a negative sign just outside the square brackets. This means the inside term should be negated, leading to \(-20 + -10\).
04

Perform the final Addition operation

Lastly, add the two negative numbers which gives a result of \(-30\).
