Topics | Explanation |
Basic Introduction of Algebra | Algebra plays a vital role in mathematics. To deal with problems in our day to day life we use algebraic symbols, numbers, and operations. |
Simplification | To simplify difficult equations we use different tricks and ways. One of the easy tricks is the application of the BODMAS rule. Here B means Bracket, O means Orders, D means Division, M means Multiplication, A means Addition, and S means Subtraction. |
Exponents
| Exponents mean Powers. When we do repeated multiplication of the same factor is called power. The symbol of an exponent is like ‘^’.For example, 2 ^ 3 is read as two to the third power. |
Quadratic Equations | Quadratic Equations are known as polynomial equations as here, the power of X is non-negative integers. Arrows, Balls, Stones, and Missiles are examples of a real-life quadratic equation. For example, when a ball is thrown in the air it goes up and slows it as it travels and then again comes down faster. |
Polynomials | The algebraic equations where exponents, variables, and coefficients can form an equation is known as Polynomials. In Polynomials, there may be different exponents and the highest exponent is known as the degree of the equation. |
