can you simplify this expression? being able to simplify expressions correctlywill help make difficult problems much easier to solve. let's see. let's start by defining "expression". an expressionis a combination of numbers and symbols.
How To Add Dissimilar Fractions And Whole Numbers, let's simplify the expression by simply goingleft to right. now, let's see what happens if we go in adifferent order. did we get the same answer? no? hmmm...theni guess order does matter! start with the parentheses.
if there is more than one set and they'rein a row, solve them in order. if one is nested inside another, solve thatone first. next, check for exponents. also known as powers,these are the small numbers behind a number. then, work through the division and multiplicationproblems from left to right. be careful to write down each step to make sure you're solvingthe right problem next. last, work through the addition and subtractionproblems from left to right, again writing each step. we started with the parentheses. next we resolvedthe exponents. then, we solved the multiplication and division, and wrapped up the additionand subtraction.
when we flatten this, it becomes pemdas. now, let's simplify that first expression.note that we're writing each step. the expression simplifies to 2! if you can remember pemdas, you can simplifyany equation, no matter how scary it looks.
