An expression is the sum (or difference) of two or more terms. Example 3x + 2y is an expression.It is a mathematical statement e.g 7=6+1 THE WHOLE THING IS AN EQUATION but the 6+1 is a expression.You can only have an expression if there is not an = signYes the 6 + 1 part is an expression. If you have an = sign or any of the other inequality symbols (,...) it is no longer an expression but a full math sentence.
It is 72m.
5(5) is 25. 3(-2) is (-6). The expression becomes 25 - (-6). When subtracting a negative number, you actually "add the opposite," so the expression is now 25 + 6 (positive 6 is "the opposite" of -6); the value is 31.
The only expression that is equal to 6 9 2 is 6 9 2.
When x = -3

it's called an expression ex. 6+3(4+2)
No, expressions do not have equal signs. Equations do, though. You can think of it like this: Equtions have EQUAl signs, while expressions do not.No, an expression cannot have an equal sign. If it were to have an equal sign, it would then be an equation.
no. an equation such as 5n = 6 has an equal sign however an expression such as 5n does not have an equal sign. it is called an expression because it is another way to EXPRESS 6
An expression has no equal sign but an open sentence does Ex:2+4=6 open sentence Ex:2x5 Expression
Yes! 6/2.4 is equal to 2.5.

A mathematical expression in its' most simplistic form, merely assigns a value to a variable. Don't confuse an expression with an equation. An equation requires a solution. An expression cannot be "solved". It only allows you to determine the value of a variable. This is the expression in words "x is equal to 3" (X is the variable which is equal to the constant number 3) This is the expression in numbers "x=3" The expression in words "y is equal to 6" (Y is the variable which is equal to the constant number 6) The expression in numbers is "y=6" I hope you understand now.
If: 4/6 = x/3 Then: x = 2
