  1. BASIC CALCULATION Short Cut Tricks) Addition


  2. About Me Peyush B.Tech, IIT Roorkee Programming, Novels & Volleyball https://unacademy.com/user/peyush29ovn


  3. Addition (Short Cut Tricks) Very easy to solve single digit addition Example:- 7+5-12, 3+4-7,9+7-16 For double digit simply use number line for addition Example:-78498-?, 74+62? , 86+74=? Draw number line and solve each of them 78498? 74+62=? 86+74=? . . 90 78 176 60 74 136 70 864 160


  4. For two double digit number whose unit and tenth place are interchanged o Example:-89+98=?, 76+67=?, 45+54=? o Multiply 11 with the addition of both unit and tenth place digit o 89+98-11*17-187 o 76+67-11 13-143 o 45+54-11 9-99


  5. . For larger numbers i.e. 4-5 digit numbers o Don't write the calculation in stack form o Simply add thousand, hundred... places and predict the upper and lower limit o Example:-63457+32146+44568+78403+84365+6385-? o Addingthousand place:-63+32-(95)+44=(139)+784217)+84-301)+6s(307) o Lower limit is 307000 and upper limit will be a maximum of 6000 more to lower i.e. 313000(because there are 6 numbers whose last 3 digits are neglected) Adding hundred place:-4+1-(5)+5=(10)+4=(14)+3=(17)+3=(20) Lower limit is 200 and upper limit will be a maximum of 600 more to lower i.e. 800(because there are 6 numbers whose last 2 digits are neglected) o o o So, Number's lower limit is 307200 and upper limit will be 307800 o Addingtenth place:-57446-(103)+68=(171)+03=(174)+65-239)+85-324) o Add this to lower limit and that will be the answer i.e. 307200+324-307524
