No man. Its 100% correct. Module 9 is wrong too. 9 is not exactly equal to 0. Thats insane. 9 is 9 ones. All numbers do not exist between 0-9 either. One is the only number that exist.
See, that is how Math works. It is by definition right, although it will often fail to apply in an useful way to specific real work situations.
I suppose technically Module 1 math is also valid, but it is not all that useful.
And dude, addition IS multiplication. Multiplication is a short cut for addition. 9x3=27.
Ssame darn thing as 9 ones, repeated 3 times. Its 27.
I stand firm. Its 100% correct. And we got tought wrong.
Excuse me?
