Order of operations is like a recipe for doing math. Just like you add sugar before baking, in math, you do multiplication before addition. So when we have 143 + 305 × 70, we first multiply 305 by 70, and then we add 143 to the result. It’s just like cooking, you need to follow the steps in the right order!
Why Does It Matter? Imagine you’re at a store and want to know how many candies you can buy. If you multiply first, you’ll get the right number of candies. But if you add first, you might end up with more or less than you need!
Examples
- You have 143 candies and buy 70 bags of 305 candies each, first count the total candies in the bags, then add your original 143.
- Adding before multiplying would be like counting all your candies first, even if they were already packed into bags.
- It's like a recipe, you need to follow steps in order for the right result.
