Combining Like Terms

Algebraic Expressions

Algebraic expressions are the building blocks of algebra, much like how LEGO bricks are to castles. They are combinations of variables and constants, connected by operations like addition, subtraction, multiplication, and division. In secondary 3 math syllabus Singapore, students learn to manipulate these expressions to simplify and solve for unknowns.

Like Terms

Like terms are terms that contain the same variable raised to the same power. Think of them as twins in algebra - they look exactly alike! For instance, in the expression '3x + 2y - 5x', both '3x' and '-5x' are like terms because they both have the variable 'x' raised to the power of 1. Combining like terms is like combining these twins - you add their coefficients (the numbers in front of the variable).

Coefficients

Coefficients are the numbers in front of the variables in an algebraic expression. They tell you how many times the variable is being used in that term. In the expression '7x + 3y - 4', the coefficients are 7, 3, and -4 respectively. When combining like terms, you add or subtract these coefficients, while the variables stay the same.

Simplification

Simplifying algebraic expressions is like tidying up your room - you combine similar things to make it neater. In algebra, this means combining like terms to make the expression cleaner and easier to understand. For example, '3x + 4x - 2x' can be simplified to '5x' by combining the like terms. This is a key skill taught in the secondary 3 math syllabus Singapore.

Equivalency

After simplifying an expression, you should end up with an equivalent expression - one that means the same thing as the original but looks different. For instance, '3x + 4x' is equivalent to '7x'.
