What is an expression? What is a expression? What is a mathematical equation?
- A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
- A mathematical expression is made up of terms (constants and variables) separated by mathematical operators.
- A mathematical equation is used to equate two expressions. Equation modelling is the process of writing a mathematical verbal expression in the form of a mathematical expression for correct analysis, observations and results of the given problem.
Given is that to find the 40% of 84.
Assume that the 40% of 84 is equivalent to [x]. Then, we can write -
x = (40/100) x 84
x = 4/10 x 84
x = 8.4 x 4
x = 33.6
Therefore, on calculation, the 40% of 84 is equivalent to 33.6.
