What do we get when we multiply 2 with 2? The answer is 4. What do we get if we multiply 7 with 7? The answer is 49. Now, what do we get if we multiply 5 with 5? We would get 25. That's true for all of us. Now closely observe the equations that we did here. We multiplied the same number twice to get an answer. The answer that we get by multiplying the number twice is called 'Square' of a number. But what if we multiply the same negative numbers with each other? Do we get a negative square? Watch our videos to learn the answer.
