which expression is equal to "three less than a number multiplied by six"?
I think it's 6x-3
Also
1*(3+7)=(1*3)+(1*7) is distributive. I just want to verify

Both of your answers are correct!
To clarify your first equation for other readers: "three less than a number" means the number minus 3, so - 3 will be at the end of the equation. "A number multiplied by 6" means the number times 6. Choose any symbol to represent "a number." Grace chose x as the symbol. So, the expression becomes 6x - 3.
The 2nd equation is an example of using the distributive property to solve a problem.
For 1*(3+7), you multiply 1 by the first term in the parentheses (1*3), then by the second term in the parentheses (1*7). Put a plus sign between the two because there is a plus sign inside the parentheses. So, 1*(3+7) = (1*3) + (1*7). If there had been
a minus sign inside the parentheses, there would be a minus sign between the two products. 1*(3-7) = (1*3) - (1*7)
Grace, it looks like you have a good handle on your math!
In an effort to connect your questions, 6x-3 could also be written as 3*(2x - 1) which equals (3*2x) - (3*1). Just something extra to think about. :)
