this is so easy i got every single question right
for #6, 'AN times E equals ABN.' So you're essentially setting A*N*E=A*B*N. You have set all the variables (A, B, E and N) to constants (1,5,3 and 0 respectively) Particularly of interest is N which is set to 0. Where N=0, for any choice of A B and E the equation must be true as anything times 0 is by definition 0. by the commutative property on the left side we have (A*E)*N and on the right we have (A*B)*N. It appears that you have attempted to divide both sides by N but because it is set to 0 you have committed a divide by zero. Just because N is displayed as a variable and not a value does not mean that you can do that.
