>>19171069Gotta be careful with teachers. Early childhood education "professionals" are some of the dumbest people around. They have the lowest IQs of any college major.
As an MIT and Ivy League educated engineer, I'm always reviewing my two sons' somework assignments. They go to private school, but there are still issues.
As for the math, its simple:
For 1/0, the answer is undefined, but approaches infinity.
For normies that don't know higher math, this can be easily shown as the following:
1/1 = 1
1/0.1 = 10
1/0.01 = 100
1/0.001 = 1000
Therefore the smaller the denominator, the larger the quotient. So 1/0 must be undefined/approaching positive infinity.
