The answer cannot be numbers equal in absolute value but with opposite signs because although they have the same absolute value they do not have the same value - as required by the question.

An example of the same value with different numbers could be 4 + 6 = 10 and 7 + 3 = 10. In both cases, the sum is 10 even though the numbers being added are different.
No, numbers can be different from each other based on their value. Numbers are used to represent quantities and can vary in their magnitude and characteristics. For example, 5 is different from 10 because they represent different quantities.
Isotopes have same number of electrons. They have same number of protons, so their atomic numbers are same. They have different numbers of neutrons resulting different mass numbers.
Mass numbers of isotopes are different.
Atoms that have the same atomic number but different neutron numbers are known as isotopes. Isotopes of an element have the same number of protons but different numbers of neutrons, leading to variations in their atomic mass.
Isotopes are atoms of the same element with the same number of protons (atomic number) but different numbers of neutrons, resulting in different mass numbers.
