Solve 51-{(29+70):[26-(9+14)]-23}*(1+3)

$$51 - \{ ( 29 + 70 ) : [ 26 - ( 9 + 14 ) ] - 23 \} \cdot ( 1 + 3 )$$

Evaluate

$$11$$

Solution Steps

Add 29 and 70 to get 99.

$$51-\left(\frac{99}{26-\left(9+14\right)}-23\right)\left(1+3\right)$$

Add 9 and 14 to get 23.

$$51-\left(\frac{99}{26-23}-23\right)\left(1+3\right)$$

Subtract 23 from 26 to get 3.

$$51-\left(\frac{99}{3}-23\right)\left(1+3\right)$$

Divide 99 by 3 to get 33.

$$51-\left(33-23\right)\left(1+3\right)$$

Subtract 23 from 33 to get 10.

$$51-10\left(1+3\right)$$

Add 1 and 3 to get 4.

$$51-10\times 4$$

Multiply 10 and 4 to get 40.

$$51-40$$

Subtract 40 from 51 to get 11.

$$11$$

Factor

$$11$$
