According to the order of operations rules, we first solve the expression in parentheses:
And we get the expression:
0.18
Solve the following exercise:
\( 12+3\cdot0= \)
Great question! While seems obvious, following order of operations is a fundamental math rule. In more complex problems like , skipping parentheses would give wrong answers!
Without parentheses, you'd solve from left to right: 0.18+1=1.18, then 1.18-1=0.18. Same answer, but the parentheses make the order crystal clear!
Yes! This is called the Zero Identity Property. Any number plus zero equals that same number: . So .
Use PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Ssubtraction. Or remember: "Please Excuse My Dear Aunt Sally!"
You probably added first, ignoring the parentheses! Remember: parentheses first, so , then .
