Answer:1. 2(8) + 2(5) = n16 + 10 = nn = 26 2. 5 x (9 + 3) = n5 x 12 = nn = 60 3. 6 + (9 - 4) = n6 + 5 = nn = 11 4. (7 x 3) + (8 - 4) = n21 + 4 = nn = 25 5. 5(8) - (10 - 6) = n40 - 4 = nn = 36 6. 8 x (53) = nn = 424 7. (93) + (3 x 2) = n93 + 6 = nn = 99 8. 5(5) + 4(4) = n25 + 16 = nn = 41 9. 12 + (108) = nn = 120 10. 15 + 9(2 x 7) = n15 + 9(14) = n15 + 126 = nn = 141
