Add, subtract, multiply, and divide

Learning Objectives Solve two-step word problems using addition and subtraction. Solve two-step word problems using multiplication and division. Solve two-step word problems involving a mix of any two operations (+, -, ×, ÷). Identify the correct order of operations in a two-step problem (multiplication/division before addition/subtraction). Use parentheses to show which part of a problem to solve first. Represent a two-step word problem with an equation using a letter for the unknown quantity. Imagine you have 3 bags with 5 apples in each, but you eat 2 apples. How many are left? 🍎 Let's find out how to solve problems with more than one step! Today, we will learn how to be math detectives and solve problems that need two steps. This is called 'mixed operations&#...

TermDefinitionExample OperationA math action. The four main operations are adding (+), subtracting (-), multiplying (×), and dividing (÷).In the problem 5 + 2, the operation is addition. EquationA math sentence that uses an equals sign (=) to show that two things have the same value.4 × 5 = 20 is an equation. Two-Step ProblemA math problem that needs two operations to find the final answer.You have 10 cookies and eat 2. Then you share the rest with 4 friends. This is a two-step problem (subtraction, then division). Order of OperationsThe special rules that tell us which operation to do first when there is more than one in an equation.In 10 - 2 × 3, the order of operations tells us to multiply first (2 × 3) before we subtract. Parentheses ( )Symbols used in an equation to group numbers and...

The Parentheses Rule Solve inside ( ) first. If you see parentheses in an equation, always do the math inside them before doing anything else. They are like a VIP section for numbers! The Multiply/Divide Before Add/Subtract Rule Solve × and ÷ before + and -. If an equation has no parentheses, look for multiplication or division. Do those operations first, then do any addition or subtraction.
