PEMDAS = Paren, Exponent, Mult, Div, Add, Sub. 1 + 10 X 2 = 21. Same as 1 + (10 x 2) = 21.

And, apparently, two symbols adjacent is supposed to imply addition instead of multiplication

If the answer to the last equation is 21, isn't there a problem with the equation above it?

Presumably, these are functioning as "tallies", like most early numeration systems used ...

look at the boots, look at the horseshoes. How many do you see in each equation.

No value stated for the symbol of one horseshoe. No solution without an assumption.

1 + 10 x 2 = 21. Multiplication before addition. (Shoe=1, Horse=10, Horseshoe=2)

Nope. 1 horse shoe does not equal 2 horse shoes. 1 boot does not equal 2 boots.

look at all 4 formulas carefully. Line 3 has 1 boot rather than 2. line 4 has one horse shoe

Correct. There is no value for 1 boot or 1 horseshoe so the last equation is unsolvable.
