# How To Solve Math Problems With Exponents

For example, in the equation 4 divided by ½ you must enter it as 4/(1/2).Then the division 1/2 = 0.5 is performed first and 4/0.5 = 8 is performed last. PEMDAS is an acronym that may help you remember order of operations for solving math equations.These...solve problems involving powers of 2 explore the patterns to investigate 2 to the power of n and how it is written.

Multiplication and Division happen at the same time, from left to right.

Addition DOES NOT always get performed before Subtraction.

However, multiplication and division have the same precedence.

In other words, multiplication and division are performed during the same step from left to right. The same confusion can also happen with "AS" however, addition and subtraction also have the same precedence and are performed during the same step from left to right.

The acronyms for order of operations mean you should solve equations in this order always working left to right in your equation.

PEMDAS stands for "Parentheses, Exponents, Multiplication Subtraction" You may also see BEDMAS and BODMAS as order of operations acronyms.

You can also include parentheses and numbers with exponents or roots in your equations.

Use these math symbols: Addition - Subtraction * Multiplication / Division ^ Exponents (2^5 is 2 raised to the power of 5) r Roots (2r3 is the 3rd root of 2) () [] Brackets You can try to copy equations from other printed sources and paste them here and, if they use ÷ for division and × for multiplication, this equation calculator will try to convert them to / and * respectively but in some cases you may need to retype copied and pasted symbols or even full equations.

For example, 5 - 3 2 = 4 and 5 - 3 2 does not equal 0.

A way to remember this could be to write PEMDAS as PE(MD)(AS) or BEDMAS as BE(DM)(AS).
