According to the rules of the order of operations, multiplication and division precede addition and subtraction.
We isolate the multiplication exercise in parentheses and solve.
Now, the exercise we're left with is:
We solve the exercise from left to right. We isolate the next part of the expression with parentheses to avoid confusion
Now, the exercise obtained is:
We continue solving from left to right and isolate the next part of the expression in parentheses.
Now, the expression obtained is:
18
Solve the following problem:
\( 15\times2\times8= \)
Mathematics has a specific order that's different from reading! Without PEMDAS rules, the expression could mean either 20 or 14 - we need consistent rules to avoid confusion.
Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). Remember: Please Excuse My Dear Aunt Sally!
Adding parentheses like is a great strategy to show which operation you're doing first! It helps prevent mistakes and makes your work clearer.
Double-check each step: , then , then , finally . Slow down and verify each calculation!
Yes! Multiplication and division have equal priority, so you work from left to right when they appear together. Same rule applies to addition and subtraction - they're equal priority too.
