What is the foundation of mathematics?
Is it the ten digits from 0 to 9?
No, it is not. Before learning to recognize these ten digits, one must learn to differentiate their magnitudes.
To determine "greater" and "lesser" is to determine "whether it belongs to the numbers less than a certain number."
Even more fundamental than numbers is logic.
"Grasping 'yes' and 'no' is equivalent to grasping the 0s and 1s in a computer. Only this... must not be lost!" While thinking, Wang Qi was interrupted by past memories several times, "Since memories are already in disarray, then simply give up arranging them!"
"Whether from a past life or this life, do not bother with them, do not even think! Anything that is 'experience,' simply discard it!"
"And if it is 'knowledge' that I cannot comprehend for the moment, also discard it all!"
