Numbers...

There are people who do very complex calculations, however, they don't even know what the word "numbers" mean.

Just for dummies: Numbers are mathematical objects used for counting or measuring.

This is what some students said when we interviewed them while they were doing complex mathematical questions:

"Numbers are...err...Something you use in your maths paper..."
"Like who donno... Let's see ah... Eh, what are numbers?"
"Simple...Numbers are just...err....Numbers lah! You know what I mean...."

This proves that many of us don't even know what numbers are although we use them in our daily lives. That's strange...
