I will explain a method that is the most easy on this planet, and a unique one.\n\nI will illustrate with the help of a simple example.\n\nEg. 4-2.\n\nDraw no. line as follows:\n\n<-6--5--4--3--2--1--0--1--2--3--4--5--6--7-->\n\nNumbers left to zero are negative integers\nand to the right are the positive ones.\n\nLocate 4 on this line. Now move 2 steps behind 4 as the operation to be carried out is subtraction.\n\nThis will give answer as 2. \n\nSimilarly for addition move the steps ahead.

I know for 11x you just have to sum two last digits and insert this sum between the last digits. Ex:\n11x11=121 (we add 1+1 and insert it between 1 and 1)\n11x13=143 (3+1 and insert it between 1 and 3)

ok i will tell u some easy method to do some two digit calculations\ni actually found them out but then later found out that some smarter guys had invented it all before\n\ncalculations with 11\n\n11*10=110\n11*11=121\n11*12=132\n\nu c it\nwrite the last digit of the no., then the sum of the digits & then the last digit\n\nbut the\n11*19=209\nlast digit 9\nsum=10\nso carry one\n1+1=2\n\nhope u got that\nthere are a lot more but iam lazy\nbut if u r interested just mail me

-12 and 10 are both correct since\n\n-12 + 1 = -11 and | -11 | is 11\n\n10 + 1 = 11 and | 11 | is 11

Plug in each of the four answers.  The only one that works is (2), because you get\n\n | 3 (-2/3) - 3 | = 5\n | -2 - 3 | = 5\n | -5 | = 5\n 5 = 5

Hint:\nDo a simple substitution u = x-5\nWhich means x = u + 5\n\nYou should get\n\n(2/5)(x-5)^(5/2) + 2(x-5)^(3/2) + C
