Math Words That Start With B List

(Parent Sarah shares: “These B-words made math vocabulary fun for my child. She loved saying them in English and Chinese!”)

Bar Graph

Definition: A bar graph is a chart representing data with rectangular bars. The length or height of each bar corresponds to the value it represents, making it easy to compare quantities visually.
Chinese Translation: 条形图
Pinyin: tiáo xíng tú
Example: We drew a bar graph to show the number of books each student read this month.

Bar Model

Definition: A bar model is a visual tool used to solve math word problems. It represents quantities and relationships with bars, helping children understand addition, subtraction, and fractions.
Chinese Translation: 条形模型
Pinyin: tiáo xíng mó xíng
Example: Using a bar model, we solved how many apples were left after sharing.

Base

Definition: The base can refer to the bottom of a shape (like a rectangle or cylinder) or the main number in a number system. In multiplication or exponents, the base is the number multiplied repeatedly.
Chinese Translation: 基数 / 底
Pinyin: jī shù / dǐ
Example: In 5³, 5 is the base of the exponent.

Base Area of a Cone

Definition: The base area of a cone is the area of its circular bottom. Calculating the base area is essential for finding the volume of a cone using the formula V=13×base area×heightV = frac{1}{3} times text{base area} times text{height}V=31​×base area×height.
Chinese Translation: 圆锥底面积
Pinyin: yuán zhuī dǐ miàn jī
Example: We measured the base area before calculating the cone’s volume.

Base Area of a Cylinder

Definition: The base area of a cylinder is the area of the circle forming its bottom (or top). This area is used to calculate the cylinder’s volume $V=\text{base area}\times \text{height}$.
Chinese Translation: 圆柱底面积
Pinyin: yuán zhù dǐ miàn jī
Example: The base area of the cylinder is πr², where r is the radius.

Base Area of a Triangular Prism

Definition: The base area of a triangular prism is the area of its triangular bottom. Knowing the base area is key to finding the prism’s volume: $V=\text{base area}\times \text{height}$.
Chinese Translation: 三棱柱底面积
Pinyin: sān léng zhù dǐ miàn jī
Example: We found the triangular base area first to calculate the prism’s volume.

Base of an Exponent

Definition: In mathematics, the base of an exponent is the number multiplied by itself repeatedly. For example, in 3⁴, 3 is the base, and 4 is the exponent.
Chinese Translation: 指数底数
Pinyin: zhǐ shù dǐ shù
Example: 2 is the base in 2⁵.

Base-Ten Numeral

Definition: A base-ten numeral is a number written in the decimal system using digits 0–9. This system is the foundation of counting and arithmetic.
Chinese Translation: 十进制数字
Pinyin: shí jìn zhì shù zì
Example: 456 is a base-ten numeral.

Benchmark

Definition: A benchmark is a reference point or standard used for comparison or measurement. In math, it helps students estimate and round numbers efficiently.
Chinese Translation: 基准
Pinyin: jī zhǔn
Example: We used 50 as a benchmark to round numbers quickly.

Benchmark Fractions

Definition: Benchmark fractions are common fractions like 1/2, 1/4, and 3/4 that serve as reference points for estimation, comparison, and mental math.
Chinese Translation: 基准分数
Pinyin: jī zhǔn fēn shù
Example: We used 1/2 as a benchmark fraction to estimate other fractions.

Binary

Definition: Binary numbers are numbers written using only 0 and 1. Computers use binary to process and store data.
Chinese Translation: 二进制
Pinyin: èr jìn zhì
Example: The binary number 101 represents the decimal number 5.

Binary Addition

Definition: Binary addition is adding numbers in binary form, using 0s and 1s. Carrying occurs when the sum reaches 2.
Chinese Translation: 二进制加法
Pinyin: èr jìn zhì jiā fǎ
Example: 101 + 11 in binary equals 1000.

Binary Division

Definition: Binary division divides binary numbers using a process similar to long division in decimal numbers.
Chinese Translation: 二进制除法
Pinyin: èr jìn zhì chú fǎ
Example: Divide 1101 by 10 in binary.

Binary Multiplication

Definition: Binary multiplication multiplies binary numbers using only 0s and 1s, following repeated addition rules.
Chinese Translation: 二进制乘法
Pinyin: èr jìn zhì chéng fǎ
Example: 11 × 10 in binary equals 110.

Bisect

Definition: To bisect means to divide a shape or angle into two equal parts. Often used in geometry to create symmetry.
Chinese Translation: 平分
Pinyin: píng fēn
Example: The line bisects the angle into two equal parts.

Brackets

Definition: Brackets are symbols ( ) used in math to group numbers or operations. Operations inside brackets are performed first.
Chinese Translation: 括号
Pinyin: kuò hào
Example: Solve the expression inside the brackets first: (3 + 5) × 2 = 16.
