Simplify terms without a calculator

Simplifying appointments is also possible without a computer, because instead of that calculator you can calculate a lot in your head.

Ways to simplify simple terms

• Terms are called arithmetic expressions in which there is Counting, Variables and arithmetic symbols there. Equal signs make two terms into one equation and connect them.
• Simplifying terms means going through them until you have made them as short as possible and ideally completely calculated with a number as the result.
• If there are no variables, but only numbers in a term, simply calculate it using the arithmetic symbols it contains.
• Please note the usual calculation rules. So parentheses come first, then possible ones Potencies, Dot before line calculation and the calculation direction as when reading from left to right.

Determine variables without a computer

• In the case of variables, there are other rules according to which you can use them Symbols simplified.
• The same letters are summarized by counting them and then applying the normal calculation rules for them. If a symbol A occurs five times and is then subtracted twice, you simply calculate five minus two and in the end you have simplified to three A.
• If there is only one letter, you just write the letter without the number one. If there are zero variables left, they are simply left out completely. In products, one does not write the point of reference.
• It is important that individual numbers and variables must not be combined and simplified with one another. Even if variables are combined as AB, for example, they must not be combined with the individual variables A and B, but are considered new, separate variables.
