According to the order of operations, we will first solve the expression in parentheses:
Now we will get the expression:
Let's solve the expression vertically:
We will be careful to solve the expression in the correct order, ones with ones and then ones with tens
And we will get:
\( 140-70= \)
Even though adding 0 doesn't change the value, you must still follow PEMDAS order! The parentheses tell you to solve 5+0 first, then multiply. This builds good habits for harder problems.
Parentheses, Exponents, Multiplication and Division (left to right), Addition and Subtraction (left to right). Always follow this order!
Think of it as 25 × 5 = (20 + 5) × 5. So:
You'd still solve everything inside the parentheses first using PEMDAS within the parentheses, then multiply by 25. Parentheses always come first!
The best 'shortcut' is to always follow PEMDAS. It prevents mistakes and works for every problem. Consistency is more important than speed!
