What is the result of 34 × 27 using the standard algorithm?

• 918

• 928

• 938

• 948

Answer explanation

To find the result of 34 × 27 using the standard algorithm, multiply the units place (4 × 7 = 28), carry over 2, then multiply the tens place (3 × 7 = 21), add the carry over (21 + 2 = 23), giving the final result of 918.

Find the product of 56 × 32 using the standard algorithm.

• 1682

• 1782

• 1792

• 1802

Answer explanation

To find the product of 56 × 32 using the standard algorithm, multiply the units digits (6 × 2 = 12), carry over 1, then multiply the tens digits (5 × 2 = 10), add the carry (10 + 1 = 11), giving the result 1792.

Multiply 47 x 58 using the standard algorithm.

• 2626

• 2726

• 2826

• 2926

Answer explanation

To multiply 47 by 58 using the standard algorithm, multiply the units digits (7 * 8 = 56), carry over 5, then multiply the tens digits (4 * 8 = 32), add the carried over 5, resulting in 3726, which is the correct answer.

Find the product of 91 and 36 using the standard algorithm.

• 3186

• 3286

• 3386

• 3486

Answer explanation

To find the product of 91 and 36 using the standard algorithm, multiply the units digits (1 * 6 = 6), then the tens digits (9 * 6 = 54), and finally add the partial products (540 + 6 = 546). Therefore, the correct product is 3286.

Multiply 52 and 49 using an area model.

• 2548

• 2558

• 2568

• 2578

Answer explanation

To multiply 52 and 49 using an area model, break down 52 into 50 and 2, and 49 into 40 and 9. Then multiply the parts: 50 * 40 = 2000, 50 * 9 = 450, 2 * 40 = 80, and 2 * 9 = 18. Finally, add all the results: 2000 + 450 + 80 + 18 = 2568.

Grace is buying 83 packs of markers, each containing 57 markers. What is the total number of markers Grace will have?

• 4631

• 4731

• 4831

• 4931

Answer explanation

To find the total number of markers, multiply the number of packs by the markers in each pack: 83 packs * 57 markers = 4731 markers. Therefore, Grace will have 4731 markers in total.
