kMaking Corrections During Calculations

•If you make a mistake when inputting a value (but did not yet press an arithmetic operator key), press k to clear the value and then input the correct one.

•In a series of calculations, press kwhile an intermediate result is displayed to clear only the last calculation per- formed.

•To change the operator key (+, ,, -, \, A w, As, etc.) you just pressed, simply press the correct operator key. In this case, the operator of the last key you press is used, but the operation retains the order of precedence of the operation for the first key you pressed.

kOverflow or Error Check

The following conditions make further calculation impossi- ble.

a. When a result (whether intermediate or final) or a total accumulated in memory is greater than ±9.999999999 1099. (“–E–” indicator appears on the display.)

b.When function calculations are performed using a value that exceeds the input range. (“–E–” indicator appears on the display.)

c.When an illogical operation (such as an attempt to calcu- late o and n while n 0) is performed during statistical calculations. (“–E–” indicator appears on the display.)

d.When an illegal mathematical operation (such as division by zero) is performed. (“–E–” indicator appears on dis- play.)
