QAnswerWorking
1(d) 35negative × negative = positive
2(a) positivean even number of negative factors gives a positive product
3(d) 18−18 + 18 = 0
4(d) 3on the number line the greatest is furthest right
5(a) −12negative ÷ positive = negative
6(b) 0−16 + 16 = 0
7(c) a × 0 = 0 for every integer adivision by zero is not defined; subtraction is not commutative
8(a) −66 factors of (−1) multiply to 1, so the answer is −6
9−11(−11) + (−28) + 28 = −11
