The 4 Times Table
If you know how to double a number, this one is easy.
4 x 3 is 3 doubled = 6, then double 6 = 12, 4x3=12
2x3=6 6+6=12 (or 2x6=12)
4x5 2x5=10 10+10=20 (or 2x10=20) 4x5=20
4x7 2x7=14 14+14=28 (or 2x14=28) 4x7=28
4x12 2x12=24 24+24=48 (or 2x24=48) 4x12=48
if you think about it 2x2=4, that is why this works.
