The 1 time table and the 67 time table. And that is it!
The sum of 67 and 78 is 145.
the sum of 67 + 13 = 80
A Partial Sum is a Sum of Part of a Sequence. You must have a sequence to find the partial sum. The regular sum of 67 + 85 is 152.
It is: 5+67 = 72
67 + 89 = 156
67 + 5 = 72
67
They are: 33+34 = 67
54 + 67 = 121 54 x 67 = 3618
