Can EV3 control 3 motors at the same time?

[KFC]

Hi, friends, 
I am a newer.
I need EV3 to control 3 motors at the same time. However, it seems that the scratch program (block) can control only 2 motors at the same time. 
Could anyone tell me how to do? (Eg. Show me a picture of your scratch  program)
Thanks a lot.

Of course it can! You can't use the dual motor block that is meant for driving vehicle wheels but you can use the motor blocks in parallel.

See e.g.:

Hi, JopieK,
Thank you so much! 
I tried to  arrange the 3 green blocks in parallel before, and I failed.
Now they are arranged in serial as shown above. And actually, they work almost at the same time. That means they are functionally in parallel, right?

Thanks!

The blocks can be arranged in parallel and motors start at the same time like a slot machine.

Hi, dr_spock, 
Thanks  a lot.

My son built a car having three motors with mecanum wheels.  He wants to control the moving by IR controller.

He usually needs to drive the three motors at the "same time".  

However, we could not arrange 3 green blocks "in parallel in an IR block" before.  Now he can arrange in serial (functionally they work as parallel) in an IR block as Jopiek suggested. And now the car can move in 8 directions and rotate clockwise and reverse.

He is very happy!

I will encourage him to try what you suggested.

Thanks again

Thank Jopiek, too.
