I could not figure out the math equation. The new data did not fit the existing equation. An equation can be a math formula or standard method.
Both words are used in similar ways, but strictly speaking, a formula is an expression, and an equation is a statement that two expressions are equal. An equation has an equals sign in it.
A formula is an equation used to derive/get a value, and the equation cannot be modified.Many math formulas include only variablesVelocity = Distance / Time (or V = D / t);The area of a rectangle is length x width or simply A = lwAmong others, the examples above do not include a number. (When one substitute a value as D, t, l or w, it's not a formula anymore)
An expression is a collection of terms which are separated by addition or subtraction symbols. Often it represents one side of an equation or a formula.
The mid-point is needed when the perpendicular bisector equation of a straight line is required. The distance formula is used when the length of a line is required.
