when you put together unequal groups,can you only add?
explain what the product of multiplication sentence is?
You need to be more specific when asking your questions. What groups? What is the "multiplication sentence"?
Please repost in more detail.
When you put together unequal groups, you have the option to both add and subtract. Adding is one way to combine unequal groups, but you can also subtract to find the difference between them.
To add unequal groups, you simply count the total number of items in each group and then add them together. For example, if you have one group with 3 objects and another group with 5 objects, you can add them together to get a total of 8 objects.
On the other hand, subtracting unequal groups involves finding the difference between them. This can be done by subtracting the smaller group from the larger group. For instance, if you have one group with 5 objects and another group with 3 objects, you can subtract the smaller group from the larger group and get a difference of 2 objects.
So, when combining unequal groups, you can choose to add the total number of objects or you can subtract to find the difference between them.
