Question

$$2 \{ 4[7+4(5.3-9)]-3(40-8) \}$$

Evaluate

$-254.4$

Solution Steps

Subtract $9$ from $5.3$ to get $-3.7$.

$$2\left(4\left(7+4\left(-3.7\right)\right)-3\left(40-8\right)\right)$$

Multiply $4$ and $-3.7$ to get $-14.8$.

$$2\left(4\left(7-14.8\right)-3\left(40-8\right)\right)$$

Subtract $14.8$ from $7$ to get $-7.8$.

$$2\left(4\left(-7.8\right)-3\left(40-8\right)\right)$$

Multiply $4$ and $-7.8$ to get $-31.2$.

$$2\left(-31.2-3\left(40-8\right)\right)$$

Subtract $8$ from $40$ to get $32$.

$$2\left(-31.2-3\times 32\right)$$

Multiply $3$ and $32$ to get $96$.

$$2\left(-31.2-96\right)$$

Subtract $96$ from $-31.2$ to get $-127.2$.

$$2\left(-127.2\right)$$

Multiply $2$ and $-127.2$ to get $-254.4$.

$$-254.4$$

Factor

$-254.4$
