20-20=25-25

4(5-5)=5(5-5)

4=5

2х2=5

4:4=5:5

4(1:1)=5(1:1)

2*2(1:1)=5(1:1) |:(1:1)

2*2=5

Answer 3

2 * 2 = 5 is not a mathematically correct statement. The multiplication of 2 by 2 equals 4, not 5. This can be easily demonstrated using basic arithmetic.

In mathematics, multiplication is a binary operation that combines two numbers to give a product. The multiplication of two equal numbers, such as 2 and 2, will always result in a product that is equal to the square of that number. In this case, 2 * 2 = 4.

To further explain this concept to students in the 6th or 7th grade, you can use visual aids or real-life examples. For instance, you can use objects like apples or pencils to demonstrate multiplication. If you have 2 groups of 2 apples, you can count them and see that you have a total of 4 apples. This helps to reinforce the concept that 2 multiplied by 2 equals 4.

In conclusion, the statement 2 * 2 = 5 is incorrect. The multiplication of 2 by 2 equals 4, not 5.
