Hi Lynden56

I would say that "2 x 2" is the special set of numbers (or technically number, "2") that produces the same results whether (1) multiplied, (2) added, or (3) raise to the power of. This is shown below.

1.) 2 x 2 = 4

2.) 2 + 2 = 4

3.) 2^2 = 4

It's just an interesting set of numbers for this reason, in my opinion. Mathematically I am sure it represents some significance as a threshold where this effect takes place, and not in higher or lower numbers. Although I can't personally explain the reason for this!

Thanks for your question!

2 x 2 = 4

This can also be thought of as adding two 2s together. If the equation was a little more complicated, such as 2 x 15 = you could find the answer by adding 2 together 15 times, resulting in 30.

2X2 is 4 if you are asking about multiplication. 2X2 also refers to a matrix with 2 columns and two rows.
