What model can you use to represent −7⋅1 ?(1 point) − (1+1+1+1+1+ + )

Question

GPT-4o mini · Answer

To represent $-7 \cdot 1$, you can use a model that shows the concept of multiplication as repeated addition. In this case, $-7$ times $1$ can be represented as adding $-1$ seven times. Here is how it looks: $$ -7 \cdot 1 = -1 + (-1) + (-1) + (-1) + (-1) + (-1) + (-1) $$ This is equivalent to saying that you're adding $-1$ a total of seven times, which results in $-7$. If you meant to represent it with a different structured notation, please provide that context, but generally, this approach works for illustrating the concept.

What model can you use to represent −1⋅7 ?(1 point) − ()

GPT-4o mini · Answer

To represent $-1 \cdot 7$, you can think about it in terms of repeated addition of negative values. Since multiplying by $-1$ means you're taking the opposite sign, you can represent $-1 \cdot 7$ as follows: $$ -1 \cdot 7 = - (1 + 1 + 1 + 1 + 1 + 1 + 1) $$ In this case, you are summing seven instances of $1$ and then taking the negative of that sum. So, the representation would be: $$ - (1 + 1 + 1 + 1 + 1 + 1 + 1) $$ This shows that $-1 \cdot 7$ equals $-7$.
