The product of a number and 7 increased by 3

Answer 1

The product of a number and 7 increased by 3 means that:

A number we will call n is multiplied by 7 and then 3 more is added to it. Since multiplication is done before addition in the order of operations, you must multiply first.

So, 7 times n +3 in algebraic form looks like 7n + 3. So that is your expression 7n + 3.

However, if they mean (the product of a number) and (7 increased by 3), then it would be :

7 increased by 3 and then multiplied by a number we will call n. This is unclear in the statement.

n (7+3).

It is difficult to interpret want is meant by the statement, so I would just explain what we did here. Both could be correct.

Answer 2

That could mean 7x + 3

or

it could mean

x(7+3) = 10 x

I'd go with 7x+3
