Endgroup Dirk Mar 29 14 at 2103. For example to multiply 2 by 5 you type this expression in a cell with no spaces. Remember the order of operations part of the grammar of mathematics by using the mnemonic Please excuse my dear Aunt Sally P parenthesis.

Because exponents hover above the. To make sense of the number sentence we can break it all down to addition. To multiply terms multiply the coefficients and add the exponents on each variable.
