If they wanted the multiplication done first they should have put it first if they wanted it done separately they should have put it in brackets. Not my fault some maths guy invented a specific order to do sums in who the fuck cares oh my god we read left to right fucking hell
Multiplication is just shorthand for multiple additions. so 2x4 is actually 4+4. If you expand out the multiplication the above equation becomes 2+4+4. It’s not arbitrary, it’s just what multiplication represents.
Math is our representation of real world phenomena. The universe is not calculating any computations when gravity takes effect. This is basic mathematical knowledge that they teach you when you first learn physics. So no, math is not real and is entirely made up.
I see what you’re saying. But what if we tweak things a little:
Math is real, it is numbers that are invented, the discreet packets in a ruler, a measuring stick. Like an imaginary line in a grid, such as the tropics and equator.
Im sorry, what? The order of operations is completely arbitrary, it just also happens to be the standart. Not having PEMDAS would simply mean we have to write equations differently. PEMDAS et al only exist to avoid ambiguity as in this image.

The fundamental way that math originated cares…
Except math isn’t real and was entirely made up. Including the order in which the operations are calculated.
Math isn’t real? The universe, and its laws of physics, disagree.

Yeah but the way you derive the order of operations is way above the average maths student.I say that, but its not really that complicated to derive, since you think in terms of the expansion of the naturals to the realsMy brain is fucking dumb
If pemdas is above the average math student that’s fucked. I learned it in 5th grade.
