The reason why people sometimes assume that the calculation 9 + 10 = 21 is as explained below.
<h3>How to calculate in number bases?</h3>
We want to find out the reason why people say that; 9 + 10 = 21
Now, the way you have explained it is one way to look at it by utilizing number bases to play around with the figures to arrive at 21.
However, another way is to use algebra trick pattern which is;
9 can be expressed as 3 * 3
Also, 10 can be expressed as 5 * 2. Thus, we now have;
(3 * 3) + (5 * 2)
The applying properties of algebra to cross multiply gives;
(3 * 2) + (5 * 3)
= 6 + 15
= 21
Now, though your explanation arrived at 21 and mine also 21, but those are not correct mathematical methods as 9 + 10 must be equal to 19 and not 21.
