Math Problem Statement

[(72 − {−41}) − 5 × 2] ÷ (80 ÷ 10)

Solution

Let's solve the expression step by step:

Given expression:
(72(41))5×28010\frac{(72 - (-41)) - 5 \times 2}{\frac{80}{10}}

  1. Simplify inside the parentheses: 72(41)=72+41=11372 - (-41) = 72 + 41 = 113 So the expression becomes: (113)5×28010\frac{(113) - 5 \times 2}{\frac{80}{10}}

  2. Perform the multiplication: 5×2=105 \times 2 = 10 Now, the expression is: 113108010\frac{113 - 10}{\frac{80}{10}}

  3. Simplify the subtraction: 11310=103113 - 10 = 103 The expression simplifies to: 1038010\frac{103}{\frac{80}{10}}

  4. Simplify the division in the denominator: 8010=8\frac{80}{10} = 8 Now the expression is: 1038\frac{103}{8}

  5. Perform the final division: 1038=12.875\frac{103}{8} = 12.875

So, the final answer is: 12.87512.875

  1. How would the result change if the subtraction in the numerator was different?
  2. What if the multiplication factor was increased to 10 instead of 5?
  3. Can you simplify the division before handling other operations? How would that impact the result?
  4. How does the order of operations (PEMDAS/BODMAS) affect the solution?
  5. What happens if the division in the denominator is changed to multiplication?

Tip: Always simplify expressions inside parentheses first to avoid mistakes in more complex calculations.
