Order of Operations in Mathematics follow this following rule :
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:
[tex]1.0 \times 10 - 154.2 \times 10 - 7[/tex]
[tex]= (1.0 \times 10) - (154.2 \times 10) - 7[/tex] → multiplication first
[tex]= (10) - (1542) - 7[/tex] → substraction from left to right
[tex]= - 1532 - 7[/tex]
[tex]= -1539[/tex]
This result could be verified by using scientific calculator.
