Here are some. You can find more.\n\ny = -2/3x + 4 (meaning -2/3 * x + 4)\n\nx ... -6 ... -3 ... 0 ... 3 ... 6\ny .... 8 .... 6 .... 4 ... 2 ... 0\n\ny = 3/2x - 3 (meaning 3/2 x - 3)\n\nx ... -4 ... -2 ... 0 ... 2 ... 4\ny ... -9 ... -6 .. -3 ... 0 ... 3\n\nx + 2y = -4 (ie y = -1/2 x - 2)\n\nx ... -6 ... -4 ... -2 ... 0 ... 2\ny .... 1 .... 0 ... -1 ... -2 .. -3

2+2=1 (mod 3)\n\nNothing is flawed.\nIn natural numbers we always have 2+2=4.\n\nPS.\nJust as a joke for mathematical analysis students:\n2+2=5 for sufficiently large values of 2

x^2+1/x^2\n=(x+1/x)^2-2\n=4-2\n=2\naliter\nby reasoning we can say x=1\nso x^2+1/x^8\n=1+1\n=2

2.  \nOrder of operations says, since there are no brackets, you do multiplication and division first in the order they appear, 2*2 = 4, 4/2 = 2, then addition/subtraction in the order they appear, so 2+2-2 = 2.

2(x^2-4x)-1=\n2(x^2-4x+4) -8-1=\n2(x-2)^2-9

that works... so does this:\n\n-2 x -1 x 1 x 2 x 3 = 12\n\n-2*-1=2\n2*1=2\n2*2=4\n4*3=12

Observe:\nsum= 4+12+24+40+60+.....+t(n-1)+t(n)\nsum=       4+12+24+40+.....+t(n-2)+t(n-1)+t(n)\nSubtracting,\nt(n)=4+8+12+16+20+.........upto n terms\n      = n/2[2*4+(n-1)*4]\n      = n/2[4+4n]=n[2+2n]

Even though somebody told you the answer, I'm going to explain how to do it so you know on other problems. \n\n\n4(3y+2m+1)=\n\nYou have to take the number outside of the parenthesis, and multiply it to all the other numbers.\n\nFirst you do 4 x 3y, because 3y is the first term. \nThat comes out to 12y. \n\nThe next one is 2m, so 4 x 2m= 8m\n\nThe last term is 1, so 4 x 1=4.\n\nAdd up all the numbers and the answer comes out to 12y+8m+3\n\nApply the same method to the 2nd problem\nHope this helps!
