Like terms can be added or subtracted.
5 Apples + 6 Apples = 11 Apples
Let A = An Apple: 5A + 6A = 11A
However, if the terms are not like, you cannot add or subtract them.
5 Apples - 3 Bananas = ????
Let A = An Apple, B = A Banana: 5A - 3B = ???
Like terms should share the same units, power, coefficients etc.
Like Units:
5 in + 3 in = 8 inches
5 in + 1 foot = 5 in + 12 in = 17 in <--- here we had to convert a unit
Unlike Units:
5 inches + 9 seconds = ???
3 rubber bands + 1 light year = ???
Like Powers:
5A2 + 9A2 = 14A2
6 square feet + 4 square feet = 10 square feet
Unlike Powers:
5A2 + 5A3 = (5A2)(1+A) = ???? <--- i was able to simplify a little here, but still not combine all terms
6 meter/second + 1 meter/second2 = ???
Like Coefficients:
10A + 90A = 100A
2AB + 3BA = 2AB + 3AB = 5AB <--- this is just a multiplicative property (AB=BA)
Unlike Coefficients:
10A + 9B + 8C = ???

Why can quantities with different units never be added or subtracted bwhy can quantities with different units never be added or subtracted but can be multiplied or diviut can be multiplied or divided?
Only like terms can be added or subtracted. 10m and 1s cannot be added; but divided, 10 m/s becomes a velocity.
What is The parts of an expression that can be added or subtracted called?
It is an addend or subtrahend but almost nobody uses those terms.
How do you know if you will subtract or add in simplifying algebraic expressions?
Only like terms can be subtracted or added in algebraic expressions.
What are the math terms?
Well it depends on what you mean, in math terms will usually mean the parts of an expression that are added or subtracted but not multiplied. Ex. 3x^2+2x+4 The terms here are 3x^2, 2x, and 4.
What do you mean when you say the that an equation is dimensionally correct?
It means that the dimensions of all terms agree with the basic rules of mathematical operations. It also means that only terms with the same dimensions are added or subtracted.

Are terms 24g and 15g like terms?
Yes, because they both have the same variable at the end. They can be added and/or subtracted with ease!
