Explanation Given information: The numbers 288 , 512 , 3 , 950 , and 1 , 944 . Formula used: Use the following steps to add the numbers. Step 01: First write all the numbers in columns such that all the place values are aligned. Step 02: Add the digits in each column, starting from the right. If the total is a two-digit number then write its unit digit under the column which is added and carry the tens digit to the column to the left. Step 03: Check the addition of the number by adding the numbers again from bottom to top. Calculation: First round off the given numbers. 288 rounded to the nearest hundred is 300 512 rounded to the nearest hundred is 500 3 , 950 rounded to the nearest thousand is 4 , 000 1 , 944 rounded to the nearest thousand is 2 , 000 Now, add all the rounded numbers. To add the rounded numbers, align the numbers as, 300 500 4 , 000 + 2 , 000 _ Add, the digits in the units column, 0 + 0 + 0 + 0 = 0 , the sum of the units column is 0 . Write 0 under the units column. 300 500 4 , 000 + 2 , 000 _ 0 Now, add the digit in the tens column. 0 + 0 + 0 + 0 = 0 Write 0 under the tens column. 300 500 4 , 000 + 2 , 000 _ 00 Now, add the digits in the hundreds column. 3 + 5 + 0 + 0 = 8 Write 8 under the hundreds column. 300 500 4 , 000 + 2 , 000 _ 800 Now, add the digits under the thousands column. 4 + 2 = 6 Write 6 under the thousands column. 300 500 4 , 000 + 2 , 000 _ 6,800 The estimated sum of the given numbers is 6 , 800
