Unlike all the other math operation method, even decimal calculation can be made much easier by using the decimal calculators. Moreover the decimal calculators can be used to calculate all kinds of operations like addition, subtraction, multiplications and divisions. Adding Decimals: Adding decimals are also very easy. Its just like how you find the sum of the other numbers. Write the numbers, one below the one along with the decimal factors. Now write 0's so that the numbers have the same form. Then keep the decimal factor in the answer in your mind by adding normally. Example: Answer: 4.72 Subtraction Decimals: Subtracting decimals are also very simple and easy to calculate. Just like adding the decimals, write down the decimals and add a zero so that u get the same number of letters. Then minus regularly and put the decimal point down at the right place. Example: Subtract 1.03 from 2.14 Answer: 1.11 Multiplication Decimals: There are no much changes in decimals while multiplying. Just calculate the answer ignoring the decimal point. Later once you find the answer add all the decimal place and put the decimal point in the answer. Example: Multiply 2.24 by 5.5 Division Decimals: Like Multiplication Decimals, Division Decimals are also easy to calculate the answer by ignoring the decimal point. Then put the decimal element in the answer. Example: Divide 10.8 by 6 Answer: 1.8

Zbrajanje i oduzimanje decimalnih brojeva Uvod - decimalni brojevi Razlomci čiji su nazivnici dekadske jedinice (10,100,1000,...) zovu se decimalni razlomci. Decimalni razlomci mogu se izraziti u decimalnom zapisu kao jedna desetinka, jedna stotinka, jedna tisućinka I ostale razlomke možemo izraziti u decimalnom zapisu. To radimo proširivanjem ili dijeljenjem brojnika s nazivnikom. Primjer: Razlomci izraženi decimalnim zapisom zovu se decimalni brojevi. Svaki decimalni broj sastoji se od dekadskih jedinica, decimalne točke i decimalnih jedinica (decimala). Dekadske jedinice su lijevo, a decimale su desno od decimalne točke. Uspoređivanje decimalnih brojeva Od dva decimalna broja veći je onaj koji ima veći cijeli dio, a ako su im cijeli dijelovi jednaki veći je onaj koji ima veću desetinku, pa stotinku, ... Svaki prirodni broj može se pisati kao decimalni broj. Primjer: 3.0
