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

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.
