Table Total

Age 14 to 16 Short Challenge Level:

Adding up all of the numbers and symbols in the table
Total = + 4 + ( + 4) + 8 + + ( + 8) + ( + 8) + ( + 4) + 16

= 3$\times$ + 3$\times$ + 52

Bottom row (or last column):
( + 8) + ( + 4) = 16, so + + 12 = 16, so + = 4

Then, multiplying by 3,
3$\times$ + 3$\times$ = 12

So Total = 12 + 52 = 64

Using the rules in the table to find the total
Reds add up to 16
Yellows add up to 16         Purples add up to yellows   Total = 16$\times$4 = 64
