Can we only use the number once?\n\n9+5+26-26=14\n\n9*5-26-5=14

1.) if I am understanding this correctly that is an easy one: just start with 2 and go up by 10\n\n2, 12, 22, 32, 42...\n\n2.) the pattern for this is adding 8 more to the previous add \n\n15-3 = 12\n35-15=20\n63-35=28\n\nsee how its adding 8\n\nso the 17th number would be: 1155 and the 37th number would be: 5607

Adding and subtracting:  You use the sign from the largest number.\n\nIn your example: 8x +6x + 2 + 10\nAll are positive.  You have 14x + 12\n\nLet's say you  have 8x - 6x.  the 8 is bigger and is positive so your answer is positive.  It's 2x.\n\nNow try 6x - 8x.  The 8x is negative and is the larger number.  So it is going to be negative.  The answer is - 2x.  \n\nIf multiplaying or dividing:\n\n+ and + is +\n+ and  - is -\n-  and -  is + \n\nYou must have to memorize those.  Remember, it's always positive unless one sign is positive and one negative.  Then it is negative.\n\nBest Wishes,\nSue

"To determine if a number is divisible by 7, take the last digit off the number, double it, and subtract the doubled number from the remaining number. If the result is evenly divisible by 7 (e.g. 14, 7), then the number is divisible by seven. This may need to be repeated several times."

yeah.....!!!! just calculate it!!! lol

as for example we will use the number of 999. 7865433\n\nround this number to ihr nearest 10 th \n\nwe look at the digit in the 100th place : if it's less than 5 we leave the number next io it ( the digit in the 10 th place ) as it is ( we don't change it ) if it 5 or more the digit in the 10 th place becomrs one more ( let say the digit { in the 10 th place } is 5  and the digit in the 100th places is 5 or more   then it become 6 ) we we round like this we drop the rest of the digits \nwe round  to the 100th and 1000th place , any place using the above rule /\n\n69 to the nearest 10th = 70\n\n496 to the nearest 100th = 500\n\n8364 to the nearest 1000th = 8000

Multiplying by 12\nImagine your number to be pre-pended with a zero. Each digit (including the prepended zero ) but the last has a neighbor, i.e., the digit on its right.\nRule: to multiply by 12: Starting from the rightmost digit, double each digit and add the neighbor. This gives one digit of the result. If the answer is greater than 1 digit simply carry over the 1 or 2 to the next operation. Example: 0316 × 12 = 3,792:\nIn this example\nthe 3 is neighbor to the prepended zero.\nthe 1 is neighbor to the 3.\nthe 6 is neighbor to the 1.\nthe last digit 6 has no neighbor.\n6 × 2 = 12 (2 carry 1)\n1 × 2 + 6 + 1 = 9\n3 × 2 + 1 = 7\n0 × 2 + 3 = 3\nInstead of pre-pending a zero, you can think that the first digit only needs to be copied, adding any carry.\n\nMultiplying by 11\nRule: to multiply by 11, recopy the last digit. Then, two by two, add digits next to each other. Recopy the first digit.\n\nExample: 3,422 × 11 = 37,642\n\nRecopy 2\n2 + 2 = 4\n4 + 2 = 6\n3 + 4 = 7\nRecopy 3\n\n\nMultiplying by other numbers\nThe 'halve' operation has a particular meaning to the Trachtenberg system. It is intended to mean "half the digit, rounded down" but for speed reasons people following the Trachtenberg system are encouraged to make this halving process instantaneous. So instead of thinking "half of seven is three and a half, so three" it's suggested that one thinks "seven, three". This speeds up calculation considerably.\n\nIn the same way the tables for subtracting digits from 10 or 9 are to be memorized.\n\nMultiplying by 5\nRule: to multiply by 5: \nTake half of the neighbor \nAdd numbers up, two by two \nAdd 5 if number is odd \n[edit]\nMultiplying by 6\nRule: to multiply by 6: \nAdd half of the neighbor to each digit. \nIf the result is odd, add 5. \n\nMultiplying by 7\nRule: to multiply by 7: \nDouble each digit. \nAdd half of its neighbor. \nIf the result is odd, add 5. \n\nMultiplying by 8\nRule: to multiply by 8: \nSubtract last digit from 10. \nSubtract 9 from the other digits. \nAdd result to the neighboring digits on the right. \n\nMultiplying by 9\nRule: to multiply by 9: \nSubtract the last digit from 10. (Ex.: 10 - 3 = 7) \nSubtract the middle numbers from 9, and add to the number to the right. \nTake away 1 from the first number.

Adding a negative number is the same thing as subtracting a positive number. Picture a number line. +2 means to move right 2 spaces. -4 means to move left 4 spaces. You end up on the left side 2 spaces from 0. This is -2.

I tried to calculate it for you on the website below, but I don't know how old you are, so you will have to do it yourself.

Simply multiply\n9 * 8 * 7 * 6\nBecause the first number can be 1-9 but not zero and the second number can be 1-9 but one number has already been used and so on and so forth.\nHope it helps.

why should "balance after" add up to anything like the same number?   Try this:\n\nwithdrawal..... balance after\n99..............1\n1...............0\ntotal=100......total=1

Ten numbers per line, add 'em up and divide by 10.\n\nYou should get these means for the four sets:\n\n0.138, 0.172, 0.184, 0.156\n\nBe careful, since not all the numbers may show up on Yahoo unless you put your mouse pointer on the line.

adding two positive integers you just add like normal number\nand the same thing with subtracting two negetive integers except u add a - sign. then with adding one positive and one negetive u subtract the two numbers and whichever number is bigger u would add negetive or positive to the answer\nex. -9+4=\n9-4=5\n9 is the bigger number\nso ur answer is -5\n\nsubtracting integer u keep the first number, do the opposite sign, the last number u switch, like if ur last number is a negetive then u wiould change it to a positive and visa versa\nex. 7-(-2)=\nleave the 7\nswitch the minus to a plus +\nchange the negitive 2 to a positive 2\nso it would be 7+2=9

Easy.  You think of any number X.\n\nThey make you add 23, add 16, subtract 17, add 2, add 14 and subtract you number.\n\nSo the answer you will always get it\n\nX + 23 + 16 - 17 + 2 + 14 - X = 38\n\nAlgebra is fun!!! lol...NOT
