Answer

$$31$$

Work Step by Step

To simplify this expression, we follow the order of operations, so we need to multiply or divide from left to right. Multiply $4 \times 6$ first: $$24 \div 2 \times 3 + (-5)$$ Then, divide $24$ by $2$: $$12 \times 3 + (-5)$$ Then, multiply $12$ and $3$: $$36 + (-5)$$ Subtract $5$ because a positive sign and a negative sign equal a negative sign: $$36 - 5$$ Subtract: $$31$$
