Key:
1 Horse = 10
1 Horseshoe = 2
1 Boot = 1

Once you know the value of each item, the trick is remembering the correct order of operations in the last line. Following PEMDAS (parentheses, exponents, multiplication/division, addition/subtraction) gives you this solution:

1 + 10 x 2
1 + (10 x 2)
1 + 20 = 21
