# Math Symbol Definitions

Symbol is denoted the unspoken words in math. Symbol can be explained as the operation which helpful to make the expression. The symbol in the expression has to make definitions for the expression. In this article, we see about the math symbols and its definitions and how to use the math symbols in expression. Prepare for Math Symbol Definitions:

Prepare Basic Math Symbol:

Basic Math Symbol Spell - math Symbol Math Symbol in expression Definitions - Math expression + (addition) Plus, or A + B = C Add the A and B to get C

- (subtraction) Minus A – B = C Sub the A and B to get C

× (Multiplication) times A × B = C Product of two value A and B is C ÷ (Division) Divided by A ÷ B = C A is divided by B to get C ∑ (summation) The summation of Sum the given format up to infinity ∞ Infinity 1, 2, 3, 4, 5, 6, …∞ Infinity means no end

% (percentage) Percent 0.32 % 32 %

± (plus / minus sign) Plus or minus 640 kps ± 10 % Expression of range or tolerance ^ (carrot) Power or exponent form 2^4 = 16 2 × 2 × 2 × 2 = 16 = Equal 2 = (3 -1) 2 is equal to the (3 -1)
