1 about == more than or fewer / less than

2 具体数字+ or so == about - - -
He arrived five days OR SO ago.
3 more or less == somewhat

3+3=6 -------Three plus three is six
3-3=0--------Three minus three is zero
3 X 3 = 9 ------Three times three is nine
3 / 3 == 1 -----Three divided by three is one.

about用于句中；more or less用于句末，前要用逗号隔开；or also用于句末，不用逗号隔开。

about是大约
more or less是或多或少
or so是大约

加减乘除 plus/add , minus, multiply, divide
