Maths Super Challenge 33

14 May 2020

We need to make the hundreds digit as small as possible to make the smallest sum. They have to be different non-zero digits so let's try 1,2 and 3.

Now look at the tens digit. Well that can be 0 so A can be zero.

Now look at the ones digit. Choose the smallest digits not yet used - 4 and 5.

T, B, M are 1,2,3 and it doesn't matter which is which.
A = 0
P, N are 4,5 and it doesn't matter which is which.

So we have 
TAP + BAT + MAN
104  +  201  + 305 = 610

The smallest sum is 610.
