2+2

Since your subject is English (8th grade) and your goal is to understand, here is a detailed, step-by-step explanation in English.

Answer: 4

Step-by-step explanations

• Standard addition method

  • We are adding two single-digit numbers: 2 + 2.
  • Add the digits in the ones place: 2 + 2 = 4.
  • No carrying is needed because the sum is a single digit.
  • Therefore, 2 + 2 = 4.

• Counting-on method

  • Start at 2 and count two more: 3, 4.
  • After counting two steps, you land on 4.
  • So, 2 + 2 = 4.

• Number line method

  • Find the point 2 on the number line.
  • Move two steps to the right: 3, then 4.
  • You land on 4, so 2 + 2 = 4.

• Visual/objects method

  • Imagine two apples plus two more apples.
  • Total apples: 4.
  • So, 2 + 2 = 4.

• Quick language note

  • The expression is read as: “two plus two equals four.”

Key idea

• This is an example of basic addition with small numbers. The result is obtained by combining two groups of two units, giving a total of four units. The operation is commutative, so the order doesn’t matter (2 + 2 = 4, and the sum is the same).
