8*5 - 7*2 = 40 - 14 = 26
Here we will explain two ways of looking at this problem to solve it. How many times does 3 go into 26? is the same as asking How much is 26 divided by 3? ...
Remember in multiplication that A x B is the same as B x A? Well using this rule we can write that 13 x 2 = 26 and 2 x 13 = 26.
13/10 = 130/100 = 26/20
13X2
23,3 19,7 13,13
Since any two letters of the alphabet do not duplicate each other, then the number of arrangements of any two letters is the same as the number of permutations of 26 things taken 2 at a time. That is 26! / (26 - 2)!, or 26! / 24!, or (26) (25), or 650.
Assuming you are using the standard English alphabet, the number of combinations you can make are: 26 x 26 = 676 combinations.
26 x 3 13 x 6
26*25*24*23/(4*3*2*1) = 14950
3 and 23 are two prime numbers having a sum of 26.
