Solve [11+42div7-(3*2-7)]-(-12-7)

$$[ 11 + 42 \div 7 - ( 3 \cdot 2 - 7 ) ] - ( - 12 - 7 )$$

Evaluate

$$37$$

Solution Steps

Divide 42 by 7 to get 6.

$$11+6-\left(3\times 2-7\right)-\left(-12-7\right)$$

Add 11 and 6 to get 17.

$$17-\left(3\times 2-7\right)-\left(-12-7\right)$$

Multiply 3 and 2 to get 6.

$$17-\left(6-7\right)-\left(-12-7\right)$$

Subtract 7 from 6 to get -1.

$$17-\left(-1\right)-\left(-12-7\right)$$

The opposite of -1 is 1.

$$17+1-\left(-12-7\right)$$

Add 17 and 1 to get 18.

$$18-\left(-12-7\right)$$

Subtract 7 from -12 to get -19.

$$18-\left(-19\right)$$

The opposite of -19 is 19.

$$18+19$$

Add 18 and 19 to get 37.

$$37$$

Factor

$$37$$
