The video introduces the give-and-take strategy for addition, which involves adjusting numbers to reach 'friendly' numbers that are easier to add mentally. The strategy is demonstrated through several examples, starting with smaller numbers and progressing to larger ones. By adding to one number and subtracting from the other, the process simplifies mental calculations, making it easier to handle both small and large numbers.

What is the primary goal of the give-and-take strategy in addition?

• To find the largest number possible

• To simplify addition by reaching friendly numbers

• To confuse the calculation process

• To teach subtraction alongside addition
