Number of beads that Sam had before = 9 u
Number of beads that Sam gave to Liam = 2 u
Number of beads that Sam gave to Ethan = 2 u
Number of beads that Sam gave to Japheth = 1 u
Number of beads that Sam had left = 4 u
4 u = 36
1 u = 36 ÷ 4 = 9
Number of beads that Sam had at first
= 9 u
= 9 u x 9
= 81
