Mathematics

We have learned how to solve a problem like 7 x 9. We know that the answer is 63. But what do we do when we have a problem like 4 + 10 x 3? This is what we will learn next!

Over the next few weeks we will be learning the **Order of Operations**. As we have discussed in class, an "operation" in mathematics is what we use to describe addition, subtraction, multiplication, or division. When we have a problem with more than one operation, we have to know in what order to solve the operations. There are three rules when solving problems that have more than one operation in them: Example: How do we solve 3 + 6 x 2? Multiplication before Addition: First, 6 x 2 =12, then 3 + 12 = 15
 * **Rule 1:** || First perform any calculations inside parentheses. ||
 * **Rule 2:** || Next perform all multiplications and divisions, working from left to right. ||
 * **Rule 3:** || Lastly, perform all additions and subtractions, working from left to right. ||

Next week, we will learn how to solve problems that include parentheses.
