Multiplication is helps to add a number multiple times. The meaning of 6 x 5 is 6 + 6 + 6 + 6 + 6.
<h3>What is multiplication?</h3>
Multiplication tells us the number of times a number is been added to itself. For example, 3 x 2 = 3 + 3 = 2 + 2 + 2
Given to us
5 x 6
As we have already discussed that multiplication is the number of times a number is been added to itself. therefore,
5 x 6 = 5 + 5 + 5 + 5 + 5 + 5 = 6 + 6 + 6 + 6 + 6
Hence, the meaning of 6 x 5 is 6 + 6 + 6 + 6 + 6.
