The most basic and common algebraic equations in math consist of one or more variables. Addition and subtraction equations. Some equations involve only addition andor subtraction.
Y a bX is the equation of a straight line where Y and X are two variables a is the y-intercept of the line and b is the slope of the line.
The standard mathematical operations are addition subtraction multiplication or division brackets grouping symbols used to indicate order of. In mathematics the trigonometric functions also called circular functions angle functions or goniometric functions are real functions which relate an angle of a right-angled triangle to ratios of two side lengths. Calculating percentages can be an easy task. Here are some suggestions.
