multiplication (or division) bingo your say a problem and if they have the correct answer they cover up a spot
I'm worried that I may not understand your question. If you mean, "What is the numerical answer to 39 squared?" IE., 39^2 or 39x39, you can type it into a calculator or use long multiplication to find out that it is 1521. If you are asking about what 'squared' is: Squaring a number is the same as multiplying it by itself 2 times, so 39^2 = 39 x 39 We can also say that the number 39 is being raised to the power of 2. Cubing a number is multiplying it by itself 3 times (to the power of 3), so 39^3 = 39 x 39 x 39 Note: The little ^ thing indicates that the 2 and 3 coming after it are smaller and written up in the corner.
