Apply PEMDAS. Thus,

7 • [6 + 10 ÷ (1 + 1)] + 4 • 5 =

7 x [6 + 10 / 2 ] + 4 x 5 =

7 x [6 + 5] + 4 x 5 =

7 x 11 + 4 x 5 =

77 + 4 x 5 =

77 + 20 =

Answer 2

97

Explanation:

7 × [6 + 10 ÷ ( 1 + 1 )] + 4 × 5

Add 1 and 1 to get 2.

7( 6 +
`(10)/(2)`) + 4 × 5

Divide 10 by 2 to get 5.

7 ( 6 + 5 ) + 4 × 5

Add 6 and 5 to get 11.

7 × 11 + 4 × 5

Multiply 7 and 11 to get 77.

77 + 4 × 5

Multiply 4 and 5 to get 20.

77 + 20

Add 77 and 20 to get 97.
