Question

29 - [ 16 + 3 .( 51 - 49 ) ] 

Answer 1

7

Answer 2

\(29-\left[16+3.\left(51-49\right)\right]\)

\(=29-\left[16+3.2\right]\)

\(=29-\left[16+6\right]\)

\(=29-22=7\)

Answer 3

\(29-\left[16+3\left(51-49\right)\right]=29-\left(16+6\right)=29-22=7\)

Answer 4

\(29-\left[16+3.\left(51-49\right)\right]\\ =29-\left[16+3.2\right]\\ =29-\left[16+6\right]\\ =29-22\\ =7\)

Answer 5

\(\text{29−[16+3.(51−49)]}\)

\(\text{=29−16−3.2}\)

\(\text{=7}\)
