| deepseekr1 | The problem requires calculating 28 × 42. Breaking it down: 1. **Method 1**: Split 42 into 40 + 2. - 28 × 40 = 1,120 - 28 × 2 = 56 - Sum: 1,120 + 56 = **1,176**. 2. **Method 2**: Standard multiplication: - 28 × 2 = 56 - 28 × 40 = 1,120 - Total: 56 + 1,120 = **1,176**. 3. **Verification**: Using (30−2)(40+2): - 30×40 + 30×2 − 2×40 − 2×2 = 1,200 + 60 − 80 − 4 = **1,176**. All methods confirm **1,176**, matching option **D**. Answer: D |

| wenxinyiyan | D Explanation: To find the value of the expression 28 x 42, we multiply the two numbers together. 28 x 42 ----- Start by multiplying the digit in the units place of the bottom number (2) by each digit in the top number (28): 2 x 8 = 16 (write down the 6 and carry the 1) 2 x 2 = 4, plus the carried 1 is 5 So far, we have: 28 x 42 ----- 56 (this is the partial product for the units place) Next, multiply the digit in the tens place of the bottom number (4) by each digit in the top number (28), and this time write down the result shifted one place left (i.e., tens place and hundreds place): 4 x 8 = 32 (write down the 2 and carry the 3) 4 x 2 = 8, plus the carried 3 is 11 (write down the 1 and carry the 1) Combining this with the previous partial product, we get: 28 x 42 ----- 1176 Therefore, the value of the expression 28 x 42 is 1,176, which matches option D. |

| zhipu | To find the value of the expression \( 28 \times 42 \), we can perform the multiplication. First, break it down using the distributive property: \[ 28 \times 42 = 28 \times (40 + 2) = (28 \times 40) + (28 \times 2) \] Calculate each part: \[ 28 \times 40 = 1120 \] \[ 28 \times 2 = 56 \] Add the results together: \[ 1120 + 56 = 1176 \] So, the value of the expression \( 28 \times 42 \) is 1176. Therefore, the correct answer is: D. 1,176 |
