10 Mdcat Tips On HOW TO SOLVE PHYSICS’ CALCULATIONS QUICKLY WITHOUT USING CALCULATOR by HASSAAN RASHEED SMC’25 As we all know that calculator is not allowed in MDCAT , and the calculation part of Physics mcqs is very time-consuming , So I am going to share some of the tips and tricks that i have been using in my calculations , i hope it will help you . # 1) Solving squareroots without calculator Sbsy pehly to apko atleast 1-20 tk k squares ki values yaad honi chahiyen . 1-10 are quite easy so i am starting from 11. • 11 square = 121 • 12 square = 144 • 13 square = 169 • 14 square = 196 • 15 square = 225 • 16 square = 256 • 17 square = 289 • 18 square = 324 • 19 square = 361 • 20 square = 400 Next apko kuch square roots ki values yaad hona lazmi hain • Square root 2 = 1.4 • Square root 3 = 1.7 • Square root 5 = 2.2 • Square root 7 = 2.6 ~ in values ko yaad krny sy ap bari values k sqaureroots ko easily nikal skty hain , mtlb agr 21 ka squareroot apko find krna ha to ap usk multiples dhundein jo k 7 or 3 bnty hain or is trah un dono k sq.roots ki values ko multiply krny sy apk pas sq.root21 ki value ajay gi ~ or agr apko koi aesa number ajay squareroot nikalny k liy jisk multiples k squareroots apko yad nahi hain , to tb aap “Approximation method” use kryn gy , like agr apko 29 ka square root chahiy to aap dekhyn k isk qareeb qareeb konsy whole-number k squares arhy hain . ab 29 k 1 trf 5 ka square 25 ata ha , or dusri trf 6 ka square 36 ...
