Question 4 In each of the sets of expressions below, identify those that have the same value. Do not evaluate them, but rather use your understanding of terms. (a) 319 + 537, 319 – 537, – 537 + 319, 537 – 319 Expressions: 319 + 537 319 – 537 –537 + 319 = 319 – 537 537 – 319 Thus, Expr 2 and Expr 3 have same value: Question 4 In each of the sets of expressions below, identify those that have the same value. Do not evaluate them, but rather use your understanding of terms. (b) 87 + 46 – 109, 87 + 46 – 109, 87 + 46 – 109, 87 – 46 + 109, 87 – (46 + 109), (87 – 46) + 109 Expressions 87 + 46 – 109 87 + 46 – 109 87 + 46 – 109 87 – 46 + 109 87 – (46 + 109) = 87 – 46 – 109 (87 – 46) + 109 = 87 – 46 + 109 Thus, Expr 1, 2, 3: ✅ same Expr 4 and 6: ✅ same structure (sub + add) Expr 5: ❌ different (whole sum being subtracted)
