Juan says, when you put together unequal groups, you can only add. is he correct ? explain.

 The answer is yes.

Step-by-step explanation: According to Jaun, when we put together unequal groups, we can only add. We are to check whether he is correct or not.

Let us consider the addition of unequal groups and let the groups be linear polynomials (x-1), (x-2) and (x-3).

Then, adding these, we have

(x-1)+(x-3)+(x-4) = x-1+x-3+x-4 = 3x-8. Therefore, addition is the only thing that is possible here. We cannot multiply or use any other mathematical operation.

Again, let us consider the addition of equal groups (x-3), (x-3) and (x-3). Adding these, we have

(x-3)+(x-3)+(x-3) = 3x-9 = 3(x-3), i.e., addition can be written in multiplicative form too in case of equal groups.

Thus, when we put together unequal groups, addition is the only operation possible. Jaun is absolutely correct.

-12 > a

step-by-step explanation:

-11 > 1 + a

subtract 1 from each side

-11 -1> 1 -1+ a

-12 > a
