In mathematics, a term is a single mathematical expression. It could be a single number, a variable, or a combination of numbers and variables multiplied together. Understanding terms is important in algebra because they form the building blocks of algebraic expressions and equations.
Types of Terms
There are different types of terms based on their composition:
Constant Terms: These are terms that consist of just a single number. For example, 5, -3, and 2.7 are constant terms.
Variable Terms: These are terms that consist of just a single variable. For example, 3x, -2y, and 0.5a are variable terms.
Coefficient: The coefficient of a term is the numerical factor of a term. In the term 4x, the coefficient is 4. In the term -3y, the coefficient is -3.
Like Terms: Terms that have the same variables raised to the same powers are called like terms. For example, 3x and 5x are like terms because they both have the variable x raised to the power of 1.
Number and Operations: Students' work in dividing fractions shows them that they can express the result of dividing two whole numbers as a fraction (viewed as parts of a whole). Students then extend their work in grade 5 with division of whole numbers to give mixed number and decimal solutions to division problems with whole numbers. They recognize that ratio tables not only derive from rows in the multiplication table but also connect with equivalent fractions. Students distinguish multiplicative comparisons from additive comparisons.
