Only like terms can be subtracted or added in algebraic expressions.
They become positive integers for instance - - 2 = 2
Multiply out all the brackets (parentheses) and then combine like terms.
It's pretty much the exact same. Subtracting is the same as adding a negative number. Foe example, five minus three is the same as five plus negative three.
is in the weather, when u get a test its like 99\100 .... and like the prices..

Numerical expressions solely include numbers, while algebraic expressions may contain a variable like x. An example of a numerical expression is 1+2 and an example of an algebraic expression is 2x+3y=0.
to subtrct integers ,rewrite as adding opposites and use the rules for addtion of integers..

Algebraic expressions can be simplified by combining together like terms but there are no solution because they don't contain equality signs

No- adding negative numbers is like adding positive numbesr , except the answer is negative.
To add and subtract algebraic expressions the simple rule of like terms applies. In your homework that asks for the expression represents the perimeter in units of this trapezoid you will need to find the like terms and simplify.
If you are adding or subtracting two numbers in scientific notation the exponents must be the same before adding the coefficients. This is similar to 'like terms' in algebraic expressions. You can't add 5x3 and 3x2 because the exponents are not the same.
In surd form, square roots need to be have the same radical term before you can add or subtract them. However, unlike in algebraic expressions, it is possible to add or subtract square roots using approximate (decimal) values.
