It is simply a coincidence. The number 6 is from Indo-Arabic system, whereas the letter b is or Roman origin. The symbol for that sound in other alphabets is quite different.
One example: If a = b, the converse b = a is also true.
No idea what the communative property is. The commutative property for addition is that a + b = b + a. Similarly, for multiplication, a*b = b*a
Like this . . .B - 4 = 35and it is then an equation, not an expression.
It looks like a slanted number sign.
A D kind of or a B
What does Matty B's girfriend look like
associative property would look like this a+(b+c) = (a+b)+c just the switch the parenthises
like something
a flat looks like this b
Bb
pretty
b
like something
pretty
pretty
This
The less than symbol looks like this: < This is where A < B ; A is less than B
