# Mathematics - Algebra

Several arithmetic operations help solve mathematical problems like Addition, Subtraction, Division, multiplication, etc. Algebra math deals in all these concepts. Moreover, it accompanies a variable. It represents several things like an object or a letter. To describe the unknowns, quantities, etc., a Variable is used.

Let us learn algebra as an equation is a mathematical sentence with an equal sign.

e.g.; 4 + 9 = 13

Inequality is a mathematical sentence that contains symbols <, ≤, >, ≥, or ≠.

e.g.; 2x + 5y ≥ 12

Let us take a question.

E.g., Riaan wants to buy chocolates and ice creams for \$12. Each chocolate costs \$1, and the ice cream costs \$2 each. If x represents the number of chocolates and y stands for ice cream, then.

x + 2y ≤ 12

The basic algebra thinking involved in correlating and translating the situations into equations and then solving them to find the everyday problems develop mathematical reasoning in children.

## Rules and Properties of Algebra

The key to solve the algebra problem is to divide the variable on the equation's unit side. Next, you can prepare the math for the constants on the opposite side of the equation to find your variable's content. Solving advanced algebra means performing the same thing on both the equation's views.

## Rule of Symmetry

As per the law of symmetry, if a is equal to b, formerly b is also equal to a. If the left-hand side is similar to the right-hand side of an equivalent symbol, then the right-hand faction is also identical to the corresponding sign's left-hand side.
