Special Math Symbol Table Type the characters (shown below the symbol on yellow backgrounds) to obtain the indicated symbol.

Not Equal

Greater than or Equal

Less than or Equal

Squared or 2 Exponent

Cubed or 3 Exponent Deg. Multiply

Plus or Minus

Square Root

≠ ≥ ≤ ² ³ ° · ± √

<> >= <= ^2 ^3 DEG * + SQR

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 Sign Minus Sign or Subtract Sign Divide Sign Equal Sign Less Than Sign Greater 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
