Learn Class 3 Math - Computation Operations

Arithmetic is the elementary branch of mathematics that originated from the Greek word arithmos, described as a Number. The numbers are being studied, and the operations are performed like Addition, Subtraction, Division, or Multiplication.

Arithmetic operations

Arithmetic operation holds addition, subtraction, division, and multiplication.

Addition (+)

The addition is the other basic operation in Arithmetic. It means combining two or more values to create a single term. For e.g., 1+3 = 4.

The identity element of addition is 0, which involves adding 0 to any value that produces the same result. The opposite element of addition is the inverse of any value, which implies maintaining the opposite of any digit to the digit itself gives the additive identity.

Subtraction (−)

Subtraction can be identified as the inverse of addition. It measures the contrast within two values, i.e., the minuend minus the subtrahend. If the minuend is more prominent than the subtrahend, the difference is positive. If the minuend is less than the subtrahend, the outcome is negative.

Multiplication (×)

Multiplication connects two values, like addition and subtraction, into a singular value or the product. The two unique values are known as the multiplicand and the multiplier. The product of a and b is shown as a·b or a x b.

Division (÷)

The division is the inverse of multiplication. It calculates the quotient of two figures, the dividend that is divided by the divisor. The quotient is greater than one if the dividend is larger than the divisor for any well-defined positive number.
