4*4

Answer: 16 Step-by-step explanation (suitable for 8th grade, in English as requested for the English subject) 1) Read the expression - 4 × 4 means "four times four" or "four multiplied by four". - The product is the result of multiplying 4 by 4. 2) Repeated addition view - Multiplication is a shortcut for repeated addition. - 4 × 4 = 4 + 4 + 4 + 4 = 16. 3) Area model (equal-length sides) - Imagine a square with side length 4 units. - Its area equals 4 × 4 = 16 square units. - This shows why the product is 16. 4) Array model - Create an array with 4 rows and 4 columns (4 by 4). - There are 4 × 4 = 16 individual cells in total. - This visualizes the multiplication as counting objects in a grid. 5) Multiplication table reference - This is in the 4-times table. - From memory or a table: 1×4 = 4, 2×4 = 8, 3×4 = 12, 4×4 = 16. - So, 4 × 4 = 16. 6) Distributive property check - 4 × 4 can be seen as (4 × 2) + (4 × 2) = 8 + 8 = 16. - Another valid form: (2 × 4) + (2 × 4) = 8 + 8 = 16. - This confirms the result using another approach. 7) Mental math shortcut - Double 4 to get 8, then double again: 8 × 2 = 16. - Or think of 4 × 4 as (4 × 2) × 2 = 8 × 2 = 16. - These shortcuts help verify the answer quickly. 8) Real-life example - If you have 4 bags and each bag has 4 apples, total apples = 4 × 4 = 16 apples. - A practical check of the same idea. 9) Check with division - If 16 is the product, then 16 ÷ 4 = 4. - This is another way to verify the correctness. Key vocabulary (relevant to English/Math context) - product: the result of multiplication (16 in this case) - factor/multiplicand/multiplier: the numbers being multiplied (4 and 4) - times: another word for multiplication (4 times 4) - area model, array model: visual methods to illustrate multiplication If you’d like, I can provide a Russian translation of the same steps or adapt the explanation to a pure math style without English terminology.
