Solve the following equation:
Let's simplify this expression while maintaining the order of operations.
Let's start by solving what's in the parentheses:
Now we get the expression:
In the next step, to make the division easier, we'll break down 25 into two smaller factors that are divisible by 5:
Let's divide each factor in the parentheses by 5:
We'll solve each expression in the parentheses and obtain:
\( 140-70= \)
Mathematical expressions must follow the order of operations (PEMDAS). Parentheses always come first, no matter where they appear in the expression. This ensures everyone gets the same correct answer!
The colon (:) is another way to write division, just like the ÷ symbol. So means the same as .
Not always! Since is straightforward, you can solve it directly. The breakdown method is helpful for harder divisions or when teaching the distributive property.
Use the acronym PEMDAS: Parentheses, Exponents, Multiplication, Division, Addition, Ssubtraction. Remember: "Please Excuse My Dear Aunt Sally!"
You likely solved instead of . The parentheses change everything! Always solve what's inside parentheses first before doing any other operations.
