Thank you all.

b.
the way my teacher made me remember which way commutative prop of multiplication was that think of ‘commuting’ and that if you can ‘travel on way on a multiplication problem (5×7) then you ‘commute’ back the other way just the same (7×5). The 9 is just there to throw you off haha

    its B) 9+(7×5)
    you’d see that your questions adds up to 44 (since 5*7 is 35, plus a 9 is 44)
    Answer B is also 44, because nothing changed except for the order of the 7 and 5, which you know that it doesnt make a difference whether you do 7×5 or 5×7.

    switch the multiplication terms inside the () because the other term is not multiplied.

    b) 9+(7×5)
