Why Language Matters in Mathematics: Unlocking Success Through Words | Mathematics Tutor Tips

Mathematical Language

When people think of mathematics, they often picture numbers, equations, and symbols. But there’s another critical element that underpins success in math—language.

Yes, words.

Understanding the language of mathematics is just as important as knowing how to solve an equation. In fact, many students struggle not because they can't do the math, but because they misinterpret what the question is asking. This blog post explores why a strong grasp of language is essential for learning mathematics, especially at the high school level, and highlights key vocabulary students need to master.

The Connection Between Language and Mathematical Understanding

1. Decoding Instructions.

Mathematical problems—especially word problems—are full of specific terms that signal what operation or method to use. A student who doesn’t know the meaning of difference, evaluate, or simplify may do the wrong thing, even if they’re capable of solving the problem.

2. Communicating Reasoning

Modern math education emphasizes not just finding the answer, but explaining how you got it. That means students need to describe their thinking clearly using correct terminology. This is impossible without a good command of math vocabulary.

3. Translating Word Problems

Turning everyday language into mathematical expressions is a skill that requires both language comprehension and math knowledge. Understanding phrases like at least, no more than, or three times as much is crucial for forming correct equations or inequalities.

4. Understanding Precision

Mathematical language is precise. Words like product, mean, or function have specific meanings in math that may differ from everyday use. Misinterpreting them can lead to serious confusion.

Essential Vocabulary for High School Mathematics Tutors

To support learning for South African and International Mathematics Students, here are some key terms every high school student should understand and be able to use confidently:

Arithmetic & Number Operations

Terms	Explanation
Sum	The result of addition
Difference	The result of subtraction
Product	The result of multiplication
Quotient	The result of division
Factor	A number that divides evenly into another
Multiple	A number that results from multiplying another number

Algebra

Terms	Explanation
Variable	A symbol (like x) that represents a number
Expression	A combination of numbers, variables, and operations (e.g., \(2x + 5\))
Equation	A statement that two expressions are equal
Inequality	A comparison of expressions using symbols like <, >, ≤, ≥
Coefficient	The number in front of a variable (e.g., 3 in \(3x\))
Like terms	Terms that have the same variable and exponent

Geometry

Terms	Explanation
Angle	Formed by two rays with a common endpoint
Perimeter	The distance around a shape
Area	The amount of space inside a shape
Volume	Exactly equal in shape and size
Congruent	Exactly equal in shape and size

Real Examples of Language in Action

Let’s look at how vocabulary affects problem-solving:

Example 1:

“Find the sum of twice a number and seven.”

A student needs to know:

• “Sum” means addition

The correct Expression is:

Example 2:

“The perimeter of a rectangle is 48 cm. The length is twice the width. Find the dimensions.”

To solve this, the student must understand:

• What perimeter means

Set up the equation:

2(length + width) = 48, with length = 2w

Example 3:

“Write an inequality to represent: A number decreased by 3 is less than 10.”

The key is knowing:

• “Decreased by” = subtraction

• “Is less than” = <

Helping Students Master Mathematical Language

Here are a few tips for teachers , parents and tutors:

• Introduce vocabulary explicitly before diving into lessons.

• Use math word walls in classrooms.

• Encourage full-sentence explanations in class discussions.

• Incorporate reading and writing tasks that include math-specific terms.

Conclusion: Words Count in Math

Math isn’t just about numbers—it’s a language in itself. When students understand mathematical vocabulary, they gain confidence, improve their problem-solving abilities, and become better prepared for exams and real-world applications.

By giving language the attention it deserves, we unlock the true potential of mathematical learning.
