Numbers changing / to in formulas
Only just started using Numbers.
I am coming across a very weird thing
Running Numbers version 4.3.1 (5249) on MacOS 10.12.6 (16G1036)
Whenever I type / to perform a divide function Numbers changes it to a +
Very odd because it is actually performing a /
i.e. I type =(C5-C6)/C6 and it actually enters =(C5-C6)+C6
I have been searching around and cannot find any reason for doing this.
In every other app on my Mac pressing / puts a / on the screen in Numbers it puts a +
I have rebooted my Mac/ performed a PRAM reset.
I cannot find out how to fix this.
Any suggestions - thoughts would be much appreciated - this is freaking me out... :-)
