REALLY long - want to pick a random value from a table, and random symbol

Hi,

I have a long winded problem, attached. I have included what I need eventually in each column.

Questions.xlsx

I need to Create a 1000+ questions of this type.

Anyone have any ideas how to randomly select a value from the table I2:1000,L2:1000.

Also how do I make it randomly select a symbol? I want either plus, minus, multiply or divide in C2:1000 and E2:000.

Thanks in advance
