Order of operations in algebra
|
The order of operations applies in algebra in the same way as with "normal" numbers. We still calculate or work out everything inside brackets first, followed by powers, then multiplication and division, then addition and subtraction.
Remember that an algebraic expression is just a way of shortening or generalising a statement about numbers. Very often, there will be nothing to "work out" unless you know the value of the unknown amount - see substitution for more details. |
