Problem 1 Add the numbers 36 + 51 Solution Step 1: Line up the numbers vertically. Step 2: We first add the digits in ones column. 6 + 1= 7. 7 is written below ones column. Step 3: Next we add the digits in tens column. 3 + 5 = 8. 8 is written below…

Problem 1 Add the single digit numbers. Solution Adding three numbers involves two steps Step 1: We add the first two numbers; 6 + 3 = 9 Step 2: Next we add the sum to third number; 9 + 4 = 13 We write down the result So Problem 2 Add the numbers Solution Step…

Problem 1 Add the single digit numbers. Solution Method 1 Adding is just like counting in this method. Step 1: We pick a number to begin with; lets say, 5. Step 2: We count up from the starting number (5) by the number of places as the second number (3) i.e., 6, 7 and 8…

This tutorial provides comprehensive coverage of addition and subtraction of whole numbers based on Common Core (CCSS) and State Standards and its prerequisites. Students can navigate learning paths based on their level of readiness. Institutional users may customize the scope and sequence to meet curricular needs. This simple tutorial uses appropriate examples to help you…

Definition A complete or whole circle is taken as 1 and parts of the circles are represented as fractions. For example, if a circle is divided into 8 equal parts, each of the parts represents the fraction 1/8. Three parts of such a circle would represent 3/8 and on. Here we are dealing with a…

Problem 1 Jamie bought a box of fruit weighing 325 kilograms. If she bought a second box that weighed 713 kilograms, what is the combined weight of both boxes? Solution Step 1: Weight of the first box of fruit = 325 kilograms Weight of the second box of fruit = 713 kilograms The combined of the two boxes of…

Definition When the denominators of any fractions are unequal or are different those fractions are called unlike fractions. Operations like addition and subtraction cannot be done directly on unlike fractions. These unlike fractions are first converted into like fractions by finding the least common denominator of these fractions and rewriting the fractions into equivalent fractions…

Definition A unit fraction is a fraction where the numerator is always one and the denominator is a positive integer. Addition or subtraction of unit fractions can be of two types; one, where the denominators are same; two, where the denominators are different. Rules for Addition of unit fractions Rules for Subtraction of unit fractions…

Definition When we add or subtract fractions, their denominators need to be same or common. If they are different, we need to find the LCD (least common denominator) of the fractions before we add or subtract. To find the LCD of the fractions, we find the least common multiple (LCM) of their denominators. LCD can…

Adding like fractions and simplification − Formula If fractions with same denominators are to be added, we add the numerators only and keep the same denominator. If necessary, we simplify the resulting fraction to lowest terms. Subtracting like fractions and simplification − Formula If fractions with same denominators are to be subtracted, we subtract the…
