Why is mathematics not always equal?

Question

ganeshie8 · Answer

cuz, with oly 'equal' you cant do everything. 
sometimes you will be having info on 'inequalities' like age  $\le$ 15,   or  $\ge$ 20 something...   which u need to be able to interpret and make sense of

I'm not sure if i answered ur q... is that wat u looking for ? :)

You mean an equation.
In mathematics, there exists a language, an equation is not really a bunch of numbers added randomly.
Let's take an example with a physics formula:
$$K=\frac{ 1 }{ 2 }m.v ^{2}$$
That's the equation that allows me to know the kinetic energy a body posses.
The formula is telling me that it's directly proportional to the halfed mass and the velocity squared.
When we say something like:
$$x ^{3}+3x>9$$
we are saying that that equation, in a certain range of values, is greater than 9.

You mean an equation. In mathematics, there exists a language, an equation is not really a bunch of numbers added randomly. Let's take an example with a physics formula:
K=12m.v2
That's the equation that allows me to know the kinetic energy a body posses. The formula is telling me that it's directly proportional to the halved* mass and the velocity squared. When we say something like:
x3+3x>9
we are saying that that equation, in a certain range of values, is greater than 9.
