Given:

8 sets of 9 to 90

To find:

Sum of 8 sets of 9 to 90.

Solution:

To find the value of 8 sets of 9 added to 90,

We need to follow the given steps:

8 sets of 9 can be expressed mathematically as $= 8\times9$

Thus, the value of 8 sets of 9 or $8\times 9 = 72.$

Now, 90 is to be added to 8 sets of 9,  

i.e.$90 + (8\times9) = 90 + 72 = 162.$  

Hence, when 90 is added to 8 sets of 9, we get 162.
