Ah, the expanded algorithm and the standard algorithm are like two different brushes in your painting kit. The expanded algorithm breaks down the steps of a math problem into more detailed parts, like creating a rough sketch before adding colors. The standard algorithm, on the other hand, is like your trusted brush that helps you quickly solve the problem with fewer steps, much like adding the final details to bring your painting to life. Both are valuable tools in your artistic math journey, each offering its own unique approach to solving problems.
An expanded form is like 145,624 divided into like 100,000+40,000+5,000+600+20+4 and that is how you do expanded form
Concise Notation is just like standard algorithm.
for 230 in expanded notation it well look like [2x100]+[3x10]= 200+30= 230
To calculate the number of arrays that can be made out of 20 elements, we need to consider the possible combinations. Each element can either be included or excluded in the array, resulting in 2 choices for each element. Therefore, the total number of arrays that can be formed is 2^20, which equals 1,048,576.
