solve using order of operations

10 - 10 * 10 + 10

To solve this expression using the order of operations, commonly known as PEMDAS (Parentheses, Exponents, Multiplication and Division from left to right, and Addition and Subtraction from left to right), we proceed as follows:

10 - 10 * 10 + 10

First, we perform the multiplication:
10 * 10 = 100

Now we substitute the result back into the expression:
10 - 100 + 10

Then, we perform the subtraction:
10 - 100 = -90

Finally, we perform the addition:
-90 + 10 = -80

Therefore, the solution is -80.
