Use the distributive property to write the product in standard form.
3(2 − 1)

3

Step-by-step explanation:

3(2-1)=6-3=3

By the distributive property of multiplication over subtraction,

3(2 - 1) = 3(2) - 3(1)

Standard form?   I don't know what they're really talking about, let's go with:

3(2) - 3(1)

That of course equals 6 - 3 = 3

your answer is d 2,500
