Expression does not have an = sign
9 − 8 is an expression
2x + 3 is an expression
3x − 9 is an expression
4x = 10 is not an expression
4x = 10 has an = Sign
So, it is not an expression
It is an equation
Here,
9 − 8 is an expression
But it does not have a variable
So, it is an expression without variables
But here,
we will study expressions with variables
Let learn how expressions are formed
We can also
Form expressions from statements
𝑥 + 3 𝑥 + 3 z − 2 2 subtracted from z 2 − z z subtracted from 2 4 l 4 multiplied by l 𝑏/8 b divided by 8 −9p 9 multiplied by P 4𝑥 − 9 First 𝑥 is multiplied by 4 Then 9 is subtracted from Product 𝑦/3+10 Y is divided by 3 and then 10 is added to it. 4 Subtracted from 𝑥 : 𝑥 - 4 9 added to z : 9 + z t multiplied by 7 : 7t k divided by 2 : 𝑘/2 9 multiplied by c : − 9𝑐 9 multiplied by 6 and 6g + 11 then 11 is added to the product P is divided by 8 and 𝑝/8 −7 then 7 is subtracted from it.
