Create a multiplication table

Let's say you want to help a child to better understand math concepts by creating a multiplication table. 

1. Enter numbers 1-10 in cells A2 to A11 and again in cells B1 to K1.
   

2. Enter this formula in cell B2. The $ locks the value for the header row and the formula multiplies it by the value in the row.
   
   =$A2*B$1

3. Copy cell B2.

4. Select the range B2:K11.
   

5. Paste the formula into those cells (Crtl + V).
