Chapter 4: Algebra Puzzle

First, I solved the positive answer which is:

57÷3=19

so an apple = 19

next, we solve another one:

(23-19)÷2) = 2

so an umbrella = 2

Lastly, we solve another one:

19-2-2= 15.

so a star = 15.

    Hi Su En

    That's good reasoning and you've made good choice of the combinations to solve.

    Next challenge: Try using the algebraic method as shown in the post :D

    Cheers, Ms Loh.
