# Four Step Operations Problems Worksheets

How to Solve Four Step Operation Problems? We have discussed two-step and three-step problems. A two-step problem has any two mathematical operations to solve. The three-step problem has any three mathematical operations to solve for. Four-steps problem work similar to the two-step and three-step problems but with an addition of one more step. Note that all these problems have to be solved according to the PEMDAS rule. Four-step operation problems have an addition of another operation to them. They are carried out in the same way as the 2-step and 3-step problems. The 4-step problem follows the same rule of PEMDAS, which is parentheses and exponents are solved first. Following parentheses and exponents, the rest of the operations are solved. Multiplication is given priority over division, and addition and subtraction are solved next. For example, if you are given a problem, (43 + 52) x 12. You will start solving this problem by solving the parenthesis first. Within the parenthesis, you will resolve the problem for exponents first. After solving for exponents, you will move to solve addition. Once you are done with parenthesis, you will move to solve the multiplication problem outside the parenthesis.

• ### Basic Lesson

Demonstrates the rule set to follow when performing arithmetic operations. Practice problems are provided. A set of rules for arithmetic operations are devised to perform calculations involving more than one arithmetic operation. 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.

#### The Equals Invention...

Mathematician Robert Recorde invented the "equal" sign in 1557. He chose 2 parallel lines to best represent equality. The "+" and "-" signs for plus and minus were used in the 15th century to mark boxes of freight over- or underweight.
