expanded is longer standerd is just regular partial products to find like standerd means simple your level. expanded means longer to stretch, or 2 make big.
YES (i think)
I'm not entirely sure I know what you mean by "expanded algorithm" but here is a guess: 31 * 19 = (13 * 9)+(31 * 10) = 117 + 310 = 427
23 multiplied by 17 equals 391.

Yes
The expanded algorithm makes use of the partial products to fully explain place value in multiplication. The standard algorithm which is most commonly used is considered superior and less confusing.

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.

The prime factors of 136 are 2x2x2x17 (or 23x17).
92/2 = 46 46*10 = 460.
An expanded algorithm provides a detailed, step-by-step breakdown of the problem-solving process, often including explanations, intermediate steps, and justifications for each action taken. In contrast, a standard algorithm presents a more concise, streamlined version that focuses on the essential steps needed to achieve the desired outcome, often omitting detailed explanations. Expanded algorithms are useful for teaching and understanding concepts, while standard algorithms are typically used for efficiency and speed in execution.
