Use your calculator to determine the answer to the following calculation: 1.0×10−154.2×10−7

1.0 × 10 − 154.2 × 10 − 7 = -1539Further explanation

Order of Operations in Mathematics follow this following rule :

ParenthesesExponentsMultiplication and DivisionAddition and Subtraction

This rule is known as the PEMDAS method.

In working on a mathematical problem, we first calculate operation that is in parentheses, follow by exponentiation, then multiplication or division, and finally addition or subtraction.

Let us tackle the problem.

Let's write down the problem that is wanted to be solved:

→ multiplication first

→ substraction from left to right

Conclusion :1.0 × 10 − 154.2 × 10 − 7 = -1539

This result could be verified by using scientific calculator.
