Answer 2

Answer:

(3–3) + (2–4)

So (3–3) is 0 and (2–4) is -2

Therefore 0 + (-2) will be equal to (-2)

This the final answer will be -2…

Also there is another way for the solution of the same equation in which we will just interchange the numbers without changing their value… For example, here I am taking it in this way,

(3+2) + (-3-4)

It will be like, (5) + (-7)

So finally it will be 5–7 which will be, -2

Thus, here too the final answer will be (-2).
