Common Secondary 1 Algebra Questions Practice
In this practice , students will explore the most common types of Secondary 1 Algebra questions and learn effective strategies to solve them with confidence.
In primary school mathematics, students mainly work with arithmetic operations involving fixed numbers and direct calculations. However, Secondary 1 algebra introduces variables represented by letters, requiring students to work with unknown quantities and relationships instead of specific values.
Addition and Subtraction of Algebraic Expressions with Fractional Coefficients
An algebraic expression with a fractional coefficient can be expressed in fractional form such that the numerator is an algebraic expression and the denominator is a numeral.
Addition and subtraction of algebraic expressions with fractional coefficients work the same way as addition and subtraction of fractions. It can only be done when all the fractions have the same denominator.
Simple Algebraic Rules
Introduction:
Addition and Subtraction:
The terms to be added or subtracted must be alike.
When adding or subtracting like terms, we simply add or subtract the coefficients. The result is a single term.
Unlike terms cannot be added or subtracted into a single term.
Multiplication and Division:
The terms to be multiplied or divided need not be alike.
When multiplying or dividing like terms, coefficients and variables are multiplied or divided separately. The result is a single term.
Evaluation of Algebraic Expressions and Formulae
Introduction:
The variable in an algebraic expression or equation represents an unknown value.
e.g.
Variables such as a, b, h, v, t, l or any other letter are replaced with values and numeric values for expressions and equations can be found.
This process of replacement is called substitution.
