About this quiz
The seven times table is the one most people find hardest, because seven shares no factors with ten and its multiples show no easy pattern.
- There are 14 multiples of seven up to 100, from 7 to 98.
- The grid goes past the usual times table: 91 is 7 times 13 and 98 is 7 times 14.
- The last digits of the first ten multiples are all different.
- Numbers such as 27, 57 and 87 end in 7 but are not multiples of it.
