Mathematical Operations of Class 10
You are provided with substitutes for various mathematical symbols. This is called the Substitution method.
This section deals with questions on simple mathematical operations namely + and - along with others namely <, =, >, etc. These operations are coded using artificial symbols. The candidate has to make substitution of real signs and then by using DMAS formula, solve the equation.
While attempting to solve a mathematical expression, proceed according to the rule BODMAS -that is, Brackets, Of, Division, Multiplication, Addition, Subtraction.
