First, calculate the expression within the parentheses:
Now, multiply the result by 9:
Thus, the final answer is 18.
18
\( 100+5-100+5 \)
Parentheses are like mathematical containers that group operations together. They tell you exactly which calculation to do first, making math expressions clear and unambiguous!
Work from the innermost parentheses outward. Solve the deepest nested expression first, then work your way out to the outer parentheses.
Sometimes you might get lucky, but not always! Following PEMDAS/BODMAS ensures you get the correct answer every time, not just by accident.
