475+27=233

Explanation:

We are given:

475+27

Let's look at 75

25 goes into 75 3 times

325=75

So,

75=325

the square root of 25 is 5, so

75=325=53

Now, let's look at 27

3 goes into 27 9 times

39=27

So,

27=39

the square root of 9 is 3, so

27=39=33

So,

475+27=453+33

453+33=203+33=233

Recall: ab+cb=(a+c)b
