When adding integers with different signs, the solution will be

• either negative or positive, depending on which integer has the greater absolute value

• always negative

• always positive

• always zero

• negative, because both y and z are negative.

• negative, because y is closer to 0 than z.

• positive, because both y and z are negative.

• positive because z is farther from 0 than y.

• Positive, because both values are positive.

• Positive, because one value is positive and one value is negative.

• Negative, because one value is positive and one value is negative.

• Negative, because both values are negative.

A submarine was 200 yards below sea level. If it descends 48 yards further, what is the new depth of the submarine? Write a sum of integers to represent the situation.

• 200 + (-48) = 152; the submarine is 152 yards below sea level

• 200 + 48 = 152; the submarine is 152 yards above sea level

• 200 - 48 = 148; the submarine is 148 yards below sea level

• -200 + (-48) = -248; the submarine is 248 yards below sea level
