Here are the solutions to the problems. Question 1: Find the sum of; a) Step 1: Add the numbers. (+8) + (7) = 8 + 7 = 15 The sum is 15. b) Step 1: Add the numbers. (+12) + (-4) = 12 - 4 = 8 The sum is 8. c) Step 1: Add the numbers. (-12) + (-26) = -12 - 26 = -38 The sum is -38. d) Step 1: Add the numbers. (25) + (-20) = 25 - 20 = 5 The sum is 5. Question 2: Find the solutions to the following: a) Step 1: Perform the operations from left to right. (12) + (-8) + (3) = 12 - 8 + 3 Step 2: Simplify. 4 + 3 = 7 The solution is 7. b) Step 1: Perform the operations from left to right. (8) - (5) + (25) = 8 - 5 + 25 Step 2: Simplify. 3 + 25 = 28 The solution is 28. c) Step 1: Perform the operations from left to right. (-30) - (+8) - (-4) = -30 - 8 + 4 Step 2: Simplify. -38 + 4 = -34 The solution is -34. d) Step 1: Perform the operations from left to right. (145) + (-47) - (28) = 145 - 47 - 28 Step 2: Simplify. 98 - 28 = 70 The solution is 70. Question 3: Solve the following multiplication problems: a) Step 1: Multiply the numbers from left to right. (6) × (-2) × (9) = -12 × 9 Step 2: Simplify. -108 The product is -108. b) Step 1: Multiply the numbers from left to right. (-4) × (-12) × (-7) = (48) × (-7) Step 2: Simplify. -336 The product is -336. Send me the next one 📸
