This issue, Top Ten features the top ten mathematical symbols for use in algebra!
A new entry at 10, everyone’s least favourite axis… y!
At 9, allegedly resembling the British Rail logo… the not equals symbol!
The perpendicular symbol gets its angle just right this week at number 8!
A re-entry at 7: The Bee Gees with Much Less Than a woman.
It may be small but we love it: epsilon spends yet another week at number 6.
At 5, amid protests of plagiarism from alpha: the proportionality symbol.
Down two places to 4, showing it really belongs in the top ten, it’s… ∈!
Maybe its resemblance to sideburns makes it col: the floor symbol is at 3.
At 2, we’ve been searching for years and we still haven’t found it: it’s x!
And topping the charts, it’s a new entry. The perfect symbol to represent some upside down screaming: for all!
