Give me one use for math in the real world now that we hae calculators and computers which can do complicated calculatons in seconds?

pro tip you can't

Say you took a three hour trip.
You drove at sixty mph for half the trip (in distance), stopped for ten minutes, and then drove at 50 mph the rest of the way. You car gets 30mpg at both speeds. How much gas did you use?

You request from an idiot too much. OP will have a calculator with him!

Amount of gas you had at the start minus amount of gas you have at the end, if you are not retarded and think this would need a calculus.

hai guys, can somone tell me the solution to the navier-stokes equation? no worries, you can use your calculator.

The 60/50-mph-subtrips covered equal distances iff they used up 50/60 portions of the time. Therefore, I drove 3 hours*50/110 at 60 mph, then 3 hours*60/110 at 50 mph. I calculate the whole distance travelled with a calculator, then divide by 30 mpg for the gas used.

As a demonstration if what I mean, type "-2^2" into your calculator. It will most likely return -4, even though you should have gotten 4. Computers make this kind if mistake all the time, and it its up to us knowing math to catch these obvious mistakes.

Furthermore, the calculator doesn't really know what it is doing, so YOU have to know what to tell the computer to do to solve more complex problems.

Tl;dr computers are our retarded slaves, if we lose the ability to do math, the relationship reverses.

I think OP has confused "mathematics" with "arithmetic". Arithmatic isn't really as neccesary to know how to do as it used to be, though as
>>5576606
points out it's still needed for error spotting. But math is about finding and proving relationships, and without those relationships we wouldn't even know how to make a computer.
