2*2=4

Цель: понять. Задача на умножение: 2*2=4. Ниже подробное пошаговое объяснение, адаптированное под 4-й класс и английский язык.

Step 1. Read the expression in English

• 2*2 is read as "two times two" or "two multiplied by two."
• The full sentence is: "Two times two equals four."

Step 2. Understand it as repeated addition

• Multiplication is a shortcut for adding equal groups.
• 2 multiplied by 2 means two groups, each containing two items.
• If we add them: 2 + 2 = 4.

Step 3. See the result and a simple check

• Therefore, 2*2 = 4.
• You can also think of it as doubling the number 2: doubling 2 gives 4.

Step 4. Visual/real-life example

• Imagine two baskets. Each basket has two apples.
• Total apples = 2 apples + 2 apples = 4 apples.
• So, two groups of two apples make four apples.

Step 5. Quick practice note

• 3*2 would be 3 groups of two: 2 + 2 + 2 = 6.
• 2*3 would be two groups of three: 3 + 3 = 6.
• In general, multiplication is commutative: ab = ba (for these numbers 22 = 22, but it holds for many other pairs too).

Answer: 4

Дополнительно (для закрепления): попробуй объяснить вслух по-английски: “Two times two equals four. It’s two groups of two.” Это поможет связать английскую терминологию с математическим понятием.
