Math Problem Statement

Evaluate the absolute value expressions involving arithmetic operations from the given worksheet.

Solution

Let's work through the problems from the image step by step. The exercises involve absolute values and basic arithmetic operations. I'll solve a few of these, and you can let me know if you'd like the rest solved in detail.

1)

5615×8+142=?|56 - 15| \times 8 + \frac{|14|}{2} = ?

  • 5615=41=41|56 - 15| = |41| = 41
  • 142=142=7\frac{|14|}{2} = \frac{14}{2} = 7
  • 41×8=32841 \times 8 = 328
  • 328+7=335328 + 7 = 335

Answer: 335335

2)

84×41=?\frac{|8|}{4} \times |4 - 1| = ?

  • 84=84=2\frac{|8|}{4} = \frac{8}{4} = 2
  • 41=3=3|4 - 1| = |3| = 3
  • 2×3=62 \times 3 = 6

Answer: 66

3)

8×1+24×7=?| -8 | \times \frac{1 + 2}{|4|} \times |7| = ?

  • 8=8| -8 | = 8
  • 1+24=34\frac{1 + 2}{|4|} = \frac{3}{4}
  • 7=7|7| = 7
  • 8×34×7=8×5.25=428 \times \frac{3}{4} \times 7 = 8 \times 5.25 = 42

Answer: 4242

4)

7×42×105=?\frac{| -7 \times 4 |}{2} \times \frac{|10|}{| -5 |} = ?

  • 7×4=28=28| -7 \times 4 | = | -28 | = 28
  • 282=282=14\frac{| -28 |}{2} = \frac{28}{2} = 14
  • 105=105=2\frac{|10|}{| -5 |} = \frac{10}{5} = 2
  • 14×2=2814 \times 2 = 28

Answer: 2828
