7*4

Here’s a clear, step-by-step explanation suitable for a 6th-grade level (in English, as the task relates to English class but uses a math problem): What is 7 × 4? - The product 7 × 4 means “four groups of seven” or “seven groups of four.” Either way, the total size is the same: 28. Step-by-step method 1: repeated addition (four groups of seven) - Write it as 7 + 7 + 7 + 7. - Add: 7 + 7 = 14 - 14 + 7 = 21 - 21 + 7 = 28 - So, 7 × 4 = 28 Step-by-step method 2: using the commutative property (7 × 4 = 4 × 7) - 4 × 7 can be thought of as four groups of seven, which is the same as above. - Using the same addition: 7 + 7 + 7 + 7 = 28 - So, 7 × 4 = 28 Step-by-step method 3: doubling (quick check) - 7 × 4 = (7 × 2) × 2 - 7 × 2 = 14 - 14 × 2 = 28 - This also confirms the result: 28 Step-by-step method 4: area model (visual) - Imagine a rectangle with 4 rows and 7 columns (or 7 rows and 4 columns). The total number of unit squares is 4 × 7 = 28. - So, 7 × 4 = 28 Answer: 28 Extra quick check (optional) - If you know 7 × 5 = 35, then 7 × 4 is 7 less than 35, which is 28. - Or double 7 to get 14, then double again to get 28 (as shown in method 2). If you’d like, I can also present this in another format (e.g., a word problem context, an English-language explanation, or with a visual diagram).
