Question

Evaluate the expression. $$ 89-8 \cdot 5-27 $$

Short answer

22

Step-by-step solution

Multiply

Start by performing the multiplication operation in the given expression: \(89-8 \cdot 5-27\). This is done before subtraction due to the order of operations. So, this looks like: \(89 - (8 \cdot 5) - 27\). Calculation of \(8 \cdot 5\) equals to 40. Replace \(8 \cdot 5\) with 40 in the expression.

Simplify

Once you have completed the multiplication, the expression should look like this: \(89 - 40 - 27\). Now you can perform the subtraction operations from left to right to obtain the final answer.

Subtract

First, calculate \(89 - 40\), which equals to 49. Substitute this into the expression and the expression simplifies to \(49 - 27\). Now, calculate \(49 - 27\), which equals to 22.
