Math Problem Statement

Solve the expression 13 - 4 [-(3 - 5) + (-3 - 2) - (-2) * 3].

Solution

The expression from the image is:

134[(35)+(32)(2)3]13 - 4 \left[ -(3 - 5) + (-3 - 2) - (-2) \cdot 3 \right]

Let's break it down and solve it step by step:

  1. Solve inside the parentheses: 35=23 - 5 = -2 32=5-3 - 2 = -5

  2. Now substitute back into the expression: 134[(2)+(5)(2)3]13 - 4 \left[ -(-2) + (-5) - (-2) \cdot 3 \right]

  3. Simplify the negative signs and multiplication: (2)=2-(-2) = 2 (2)3=6(-2) \cdot 3 = -6

  4. Substitute and simplify: [ 13 - 4 \left[ 2 + (-5) - (-6) \right] = 13 - 4 \left[ 2 - 5 + 6 \right] ] 25+6=32 - 5 + 6 = 3

  5. Now substitute back: 134[3]13 - 4 \left[ 3 \right]

  6. Final calculation: 1343=1312=113 - 4 \cdot 3 = 13 - 12 = 1

Thus, the value of the expression is 1.

  2. Can you explain why we prioritize parentheses first when solving such problems?
  3. What is the importance of simplifying signs like (2)-(-2) to 22?
  4. How would you solve this if additional terms were added inside the brackets?
  5. What other types of operations can affect the order of solving expressions?

Tip: Always resolve the operations inside the parentheses first, and be careful with negative signs to avoid mistakes!
