Significant Figures: Rules For Arithmetic Operations

Arithmetic Math

Arithmetic is a branch of mathematics, that involves the study of numbers, operation of numbers that are useful in all the other branches of mathematics. It basically comprises of operations such as Addition, Subtraction, Multiplication and Division. Let us understand each of the operation in details.

Simple/Basic Arithmetic Operations

There are four basic arithmetic operations- Addition, Subtraction, Division and Multiplication.

1. Addition Definition Math

The addition is denoted by ‘+’ sign. It involves combining two or more numbers into a single term. It can involve any type of number whether it be a real or complex number, fraction or decimals.

Example –  4.13 + 3.87 = 8

The addition of more than two numbers, values or terms is also known as a summation of terms and can involve n number of values.

2. Subtraction Definition Math

Subtraction is denoted by ‘-‘ sign. It is almost similar to addition but is the conjugate of the second term. The addition of the term with the negative term is known as subtraction.

Example: 15 – 7

The term can also be re-written as 15 + (-7)
Adding terms we have, 8.


3. Multiplication Definition Math

Multiplication is denoted by ‘×’ or by ‘*’. It also combines with the two or more values to result in one a single value.

Example: 2 × 3 = 6

Product of two numbers says ‘a’ and ‘b’ results in a single value term ‘ab,‘ where a and b are the factors of the final value obtained.

4. Division Definition Math

The division is usually denoted by ‘÷‘ and is the inverse of multiplication. It constitutes two terms dividend and divisor, where dividend is divided by the divisor to give a single term value.

When the dividend is greater than the divisor, the result obtained is greater than 1, or else it would be less than 1.

Example: 4 ÷ 2 = 2
