To be able to communicate mathematical formulas without any ambiguity,
we will adopt the convention on the left table. This notation is the notation
used to input data into most common calculators and computer algebra
systems in general.
Example To write the expression
we would type y = ((x^3 + 4)^2 - x^6)/(x^3) Use of parentheses Be generous using parentheses. It is better to overuse them than to enter the wrong expression for not grouping expressions properly. For example,
should be typed 2^(x^2) and not 2^x^2 since the last expression is ambiguous and it could be interpreted as (2x)2 which means 22x. Similarly, 4x + 3 must be typed 4^(x + 3) and not 4^x +3 since t it would mean 4x + 3. |
