could somebody tell me the answer or order of operations to this calculation.

3cos(2 x 2)

thanks.

I assume you meant

3cos(2x²)

pick your x

square it

multiply it by 2

take its cosine

multiply by 3

press the = sign on your calculator after each step to overwrite any build-in order of operation
