Potatoes+tomatoes = salad, O=4, and T.

tomato

salad

O+O =8，S=8

O+O=A O+O should be 8, which proves that A is an integer, so it is 9 A=9.

A+A=A A+A=9+9 should be 18, but it becomes A(9), so it is carried by T+T, so T "5".

8 and 9 are s and a respectively, so they are excluded.

The possible numbers of t are 5, 6 and 7 respectively.

Suppose T=6, d = 2 p+t = SP+6 = 8 p = 2, and 2 is repeated, so it is excluded.

Assuming that T=7 and D=4 O are already 4, there are duplicates, so they are also excluded.

What's left is

T=5，S=8，O=4，A=9，D=0，P=3(P+5=9)

T+m = lt+m+1= l+10 (1is the cardinal number of A+A,10 is the result of O+O being carried) 6+M=L+ 10.

So it can be seen that M "5, 5/8/9 have owners respectively, so M= 6/7.

When M = 7, T+M = L 6+7 = 13 L =3, and p =3, so it is excluded (note that t is a decimal place here, so it becomes 6).

Only when m = 6,6+6 =12 l = 2, the whole calculation is reasonable!

The answers are O = 4, S = 8, A = 9, P = 3, M = 5, L = 2, T = 5.

I hope it helps you! (Refer to other people's answers)
