Percent of Total

To calculate what percentage one number is of another:

1.Calculate the total amount by adding all individual amounts.

2.Key in the number whose percentage equivalent you wish to find.

3.Press Z.

Example: Last month, your company posted sales of $3.92 million in the U.S., $2.36 million in Europe, and $1.67 million in the rest of the world. What percentage of the total sales occurred in Europe?

2.36Keys in 2.36 to find out what percentage it is of the number in the display.

29.69Europe had nearly 30% of the total sales.

The Power Function

Pressing qcalculates a power of a number, that is, yx. Like the arithmetic function +, qrequires two numbers:

1.Key in the base number (which is designated by the y on the key).

2.Press qand key in the exponent (which is designated by the x on the key)

3.Press }to calculate the power.

Don’t forget to press OOif you are unsure if there are any pending operations.
