More Sideways Arithmetic From Wayside School (Wayside School 2.60)

Problem 20:

g

g

Which letter represents the number one? Which letter is zero? Now solve for m.

g

Problem 21:

g

g

Notice that o x h = o (or a number that ends with o.) Also that n x h = n (or a number that ends with n.) Begin by trying to solve for h.

g

Problem 22:

g

g

Begin in the addition portion of the problem. You see that e + e = e. Therefore e has to be zero. Now look at the multiplication part of the problem. Do you see why t x t has to be less than ten?

g

Problem 23:

g

g

Notice that y x rye = rye. That should give you y. Then notice that b x e = y (or a number that ends with y.) That should give you b and e. At first you may not know which is which, but it can be worked out.

g

Problem 24:

g

g

Notice that o + m = m. You know by now that o must be zero. Now notice that a x dim equals a number divisible by one hundred. That means that im must equal either 25 or 75.

g

Problem 25:

g

g

Begin with the addition portion of the problem, and try to determine a and i. Then notice that i x y = y (or a number that ends with y.) You already know i. What’s y? (It isn’t zero.)

g
