PEMDAS
Parentheses, Exponents,Multiplication and Division(reversible), Addition and Subtraction (reversible)
PEMDAS is an acronym commonly used to remember the order of operations in mathematics. It stands for Parentheses, Exponents, Multiplication and Division (from left to right), and Addition and Subtraction (from left to right).
The order of operations is a set of rules used to determine the sequence in which mathematical operations should be performed when solving an equation.
For example, if you have the expression 6 + 3 x 4, you would use PEMDAS to solve it.
– P: There are no parentheses, so you move on to the next step.
– E: There are no exponents, so you move on to the next step.
– M: There is multiplication, so you perform the multiplication first: 3 x 4 = 12.
– D: There is no division, so you move on to the next step.
– A: There is addition, so you add the 6 to the result of the multiplication: 6 + 12 = 18.
Therefore, the final answer to 6 + 3 x 4 is 18.
It is important to follow the order of operations to get the correct answer to a mathematical problem, especially when dealing with more complex equations. Remembering the acronym PEMDAS can help you solve equations accurately and quickly.
