• hi sal, ive learnt soo much from you, I'm not that good with math but after joining khan academy I know how to multiply 10s, 100s, ect. add, subtract, and decimals, but I am really struggling to memorise the multiplication table, any tips?
• well write it down a few times that is how i learned it.
• What if you have 0 group
• Its just 0 because that is kind of like a 0
• Vote me and I'll vote you
• what if you don't know how to skip count by 8 than what do you do?
• Remember that 8 is the same as 2 groups of 4. (8 = 2 x 4) If you can't count by groups of 8, try counting by groups of 4. If that is still too hard, try counting by groups of 2 and work your way up to counting by larger numbers.

• the only way i could see the picture was by looking in a window of a mirror in a window and looking out the windows of a mirror and then looking up and looking up and seeing what was happening and then looking up and looking up to the sky in a different window of a mirror in the same room and then seeing the light from behind it is amazing to look back on the light and look at the sky and see the light coming out from the sky and the sky and the stars from above and above and the sky from above it all the light way
