**Be sure to label answers with appropriate units: $12.42, 3 IN, 87 MM, 100 FT2, etc.**

You may also type SQ IN to obtain IN2; SQ FEET or SQ FT to obtain FT2; or CUBIC IN or CU IN to obtain IN3

As a shortcut, type X3 for X3; or Y2 for Y2; also IN2 for IN2; and M3 for M3, etc.

**Standard Math Symbols (found directly on keyboard)**Plus SignMinus Sign

or Subtract Sign

Divide SignEqual SignLess Than SignGreater Than Sign

**Note: Do not put period (.) after units, so type TSP (not TSP.) for teaspoon.**

Type fractions such as 3½ as 3 1/2 or -8¾ as -8 3/4

For answers that are repeating decimals (and no rounding instructions are given),

instead of typing 0.33… or 0.66…, use 1/3 or 2/3 (since the fraction form

is the most accurate representation of the answer).

To represent X4, type X4 which will be modified to X^4, where ^ indicates raised to a power.

To obtain 28, type 2^8, where “^8” means raised to the 8th power.

Always use parentheses around numerators or denominators with two or more terms:

For Example: A + B/C is not the same as (A+B)/C
