It means to find a number that, when squared, gives you a specific number. For example, when you ask for the square root of 25, you want to know which number, squared, is equal to 25. The answer in this case is 5.
zero + zero = zero
they are equal
A negative plus a negative still gives a negative answer.
Division by 4: 4x ≤ 12 divide both sides by 4: x ≤ 3

This the number of protons, equal to atomic number.
The relevant property is the closure of the set of rational numbers under the operation of addition.
Because 5 groups of 5 added up together gives you 25.
454 = 454. No other number is equal to 454.
The number of protons gives the atomic number. The number of electrons are equal to the number protons unless the atom is ionized. The number of neutrons determines which isotope you have. Hope that helps
The operation is called addition.
The additive inverse of x is -x It is the number that, when added to the original, gives a sum equal to zero.
