APPLY one of the arithmetic operations of addition, subtraction, multiplication & division using whole numbers.
Calculator Usage, Special Keys
This chapter needs the use of the +, -, x, ÷, and = keys. While using a TI-30 calculator, the number and operation keys are entered as they are written. For instance, the addition of 3 plus 4 is entered as follows:
3 key, + key, 4 key, = key, the answer, 7, is shown
The parentheses keys permit a complicated equation to be entered as written. This saves the time or effort of rewriting the equation so which multiplication or division is performed first and addition/subtraction is performed second, permitting the problem to be worked from left to right within one pass.
