This was very helpful and I would use this again
it was helpful and help me very much
Good source!
I think it was a great way to get your mind started and it helps you get the answer and the work done positively and on paper.
I think its an amazing practice.
I came up with the same answer they did. It might also be helpful to try and make one side of the equation equal a nice round multiple of 10 first, then try to make the other side of the equation match.
2x(3+7+9)=(1+5)+(8×4)
2*(3+9)=(1+5)+(8*4) is the is the answer
2 + (3-7+9) = (1 x 5) + (8/4)
2 x (3 – 7 +9) = (1 x 5) x (8/4)
