20•5-6

To solve this expression, you need to follow the order of operations, also known as PEMDAS (Parentheses, Exponents, Multiplication and Division, Addition and Subtraction).

In this case, you don't have any parentheses or exponents, so you move to the next step.

First, perform the multiplication: 20 • 5 = 100.

Finally, subtract 6 from the previous result: 100 - 6 = 94.

So, the answer is 94.
