to remember!
3. Zero times (multiplied by) ANYTHING is Zero!
0x0=0 0x8=0
0x1=0 0x9=0
0x2=0 0x10=0
0x3=0 0x11=0
0x4=0 0x12=0
0x5=0
0x6=0
0x7=0

6. One times ANYTHING besides 0 is itself.
1x1=1
1x2=2 1x8=8
1x3=3 1x9=9
1x4=4 1x10=10
1x5=5 1x11=11
1x6=6 1x12=12
1x7=7

9. A number times 2 is double (twice) that number.
2x1=2 2x8=16
2x2=4 2x9=18
2x3=6 2x10=20
2x4=8 2x11=22
2x5=10 2x12=24
2x6=12
2x7=14

12. There are two steps when
multiplying by nines
Step 1:
9x1=0 9x8=7
Subtract one 9x2=1 9x9=8
from the 9x3=2 9x10=9
number you 9x4=3
are 9x5=4
multiplying. 9x6=5
9x7=6
13. There are two steps when
multiplying by nines
Step 2:
9x1=0 9 9x8=7 2
Next to that, 9x2=1 8 9x9=8 1
write the 9x3=2 7 9x10=9 0
number you 9x4=3 6
would need 9x5=4 5
to add up to 9x6=5 4
nine. 9x7=6 3
