What would life be without arithmetic, but a scene of horrors?
9 x 9 + 7 = 88
98 x 9 + 6 = 888
987 x 9 + 5 = 8888
9876 x 9 + 4 = 88888
98765 x 9 + 3 = 888888
987654 x 9 + 2 = 8888888
9876543 x 9 + 1 = 88888888
98765432 x 9 + 0 = 888888888
Brilliant, isn’t it?
This one goes further:
987654321 x 9 - 1 = 8888888888
9876543210 x 9 - 2 = 88888888888
