Math Blog on Identity and inverse properties

In Grade VI, while studying about the whole numbers and properties of whole numbers worksheets, we are going to learn identity and inverse properties of the whole numbers which falls under maharashtra board.
Children while discussing the properties of whole numbers, Additive and multiplicative inverse and identities cannot be overseen and for this we can take Math help online.
Identity of addition or identity of multiplication is any number which when added or multiplied to the given number does not change the value of the number, i.e. the number remains same.
We take the case of additive identity property math we say that 0 (zero) is the additive identity, i.e. if we add 0 to any whole number, the number remains same.
3 + 0 = 0
9 + 0 = 0
Here we observe that when 0 is added to 3 and 9, in both the cases the result is the original number, so 0 is the additive identity.
Similarly in case of multiplicative identity property math we have 1 as a multiplicative identity, which means that if we multiply any number by 1 the number remains same.
For e.g.: 4 * 1 = 4
 And 8 * 1 = 8
Here we observe that when both numbers 4 and 8 are multiplied by 1, the number remains unchanged. So 1 is the multiplicative Identity.
Inverse property of addition says that the number and its inverse added gives the additive identity as the result i.e. 0
 So additive inverse of 4 is -4,
So 4 + (-4) = 0 as 4 is added to -4 it results to zero.
 Similarly multiplicative inverse identity means what number to be multiplied to the given number to get multiplicative identity as the result.
  eg multiplicative inverse of 4 is 1 / 4. So 4 * (1/4) is 1.

In the next blog we are going to discuss Estimation of Solutions in Grade VI and if anyone want to know about Formulas for measurement then they can refer to Internet and text books for understanding it more precisely.
