Maths Assessment

18b x 14 + 6 = 38
b = 1 because 14 + 6 = 20 and 20 + ? = 38 and it has to be 18 or 2 times 18 or 3 times 18 and so on. It has to be that because its 18b.



9b x 17 + 5 = 31
b = 1 because 17 + 5 and like I said up there ^ it has to be 9 or 2 times 9 or 3 times 9 and so on because its 9b
