-5 + 3 = -2!
Well done to the student in question but what exactly is your question?
It would help if the question specified "Why is 2 and 5 plus 3 and 4" what!
i suppose 20 as an answer if its not a trick question.
3.
if your question says 5(y+3) or 5 * (y+3) then its 5y+15
-2+5=3
31, if the question is (5 + 6) x (3 - 2), 21, if the question is 5 + 6 x 3 - 2.
2 plus 3 equals 5.
The answer to 5 times 3 is 15. This is so because if you add 5 plus 5 plus 5 , or 3 plus 3 plus 3 plus 3 plus 3, your answer would be 15. :)
if this question is -6 times 3 plus 15 then = -21 if its -6 plus 3 plus 15 then = 12 if its -6 times 3 plus 1.5 then = -16.5 if it is -6 plus 3 plus 1.5 = -1.5
It is not possible to answer the question since there is no visible operator between 9 and 8.
3 I think the question is not 8 plus minus five, i think its 8 plus negative 5, which would still be three. ie. 8+(-5)=3 or 8+-5=3. the proper way to write 8 plus negative five is my first example
