Hi All - Hope you can help with this VR question, as I believe both answers are correct.
15(32)2 14(30)2 12( ?) 4
My daughter gets two answers, 28 or 50, depending on how she works it out.
For 50 = she does 15x2 = 30 +2. 14x2=28+ 2 and then 12 x 4 = 48 +2 = 50, so, she multiplying the numbers outside the brackets and then adding 2.
For 28 = she does 15x2 = 30 +2. 14x2=28+ 2 and then 12 x 2 = 24 +4 = 28 and here she is multiplying by 2 and adding the other number outside the bracket.
Can someone please advise which is the correct method.
Thanks !
Hi, I don't understand why she is doing "12 x 2 = 24 + 4"
She should only use the information given in the question, otherwise she would have to make illogical assumptions. I have taught my ds to only go by the information contained in the question, so the answer would have to be 50
