Simplify: 8⋅9−2⋅5
Remember to use the order of operations (PEMDAS).
Using the order of operations (PEMDAS), we calculate:
8 * 9 - 2 * 5 = 72 - 10 = 62
To simplify the expression 8⋅9−2⋅5, we need to follow the order of operations (PEMDAS).
First, we perform the multiplication.
8⋅9 = 72
2⋅5 = 10
Now, we substitute these values back into the expression:
72 - 10
Finally, we perform the subtraction:
72 - 10 = 62
Therefore, the simplified expression is 62.
