Question

$$73-[72+\{(87-9)-(69+9)\}]$$

Evaluate

$1$

Solution Steps

Subtract $9$ from $87$ to get $78$.

$$73-\left(72+78-\left(69+9\right)\right)$$

Add $69$ and $9$ to get $78$.

$$73-\left(72+78-78\right)$$

Subtract $78$ from $78$ to get $0$.

$$73-\left(72+0\right)$$

Add $72$ and $0$ to get $72$.

$$73-72$$

Subtract $72$ from $73$ to get $1$.

$$1$$

Factor

$1$
