Math can be a lot of fun, especially when you know the rules to follow! One important rule in math is called the “order of operations.” This rule helps us know which math steps to do first so we can get the right answer. Let’s learn about this rule and how it works!
When you see a math problem with different operations like adding, subtracting, multiplying, or dividing, it’s important to know which one to do first. We use a special word to remember the order: PEMDAS. Here’s what each letter stands for:
This means you do any math inside parentheses first, then exponents, followed by multiplication and division, and finally addition and subtraction. Let’s see how this works with an example!
Let’s solve the math problem 2 × 3 + 5. According to PEMDAS, we do the multiplication first:
The answer is 11!
Parentheses are like little helpers in math. They tell us to do the math inside them first, no matter what. This can change the answer, so it’s important to pay attention to them!
What if we have 2 × (3 + 5)? The parentheses tell us to add first:
The answer is 16!
When talking about math problems, it’s important to be clear about the order. If you want to say 3 × (4 – 1), you can say:
“Three times the quantity of four minus one.”
This helps others know to do the subtraction first.
Let’s solve 3 × (4 – 1):
The answer is 9!
Knowing the order of operations and how to use parentheses helps us solve math problems correctly. By following the PEMDAS rule and being clear when we talk about math, we can avoid mistakes and have fun with numbers. Whether you’re adding, subtracting, multiplying, or dividing, these tips will help you find the right answers!
PEMDAS Scavenger Hunt: Go on a scavenger hunt around your home or classroom to find examples of math problems that use different operations. Write them down and solve them using the order of operations. For example, you might find a recipe that requires you to multiply and add ingredients. Try to solve the math problem using PEMDAS and see if you get the right answer!
Parentheses Play: Create your own math problems using parentheses. Write down a simple math problem, like 5 + 2 × 3, and then add parentheses to change the order of operations, like (5 + 2) × 3. Solve both problems and see how the answers change. Share your problems with a friend and solve each other’s problems!
Order of Operations Story: Write a short story or draw a comic strip about a character who uses the order of operations to solve a problem. Maybe they are a chef who needs to follow a recipe, or a builder who needs to measure materials. Use your imagination and include math problems in your story. Share your story with the class!
