dry comfort diapers skin HUGGIES HUGGIES dry comfort Dry Comfor dlana Addition and subtraction problems We can use addition and subtraction to solve many different types of problems in mathematics. Sometimes you need to use both operations in a multi-step problem. You can also use the inverse calculations to check your answers. EXERCISE 3.6 Use addition or subtraction to solve the following word problems. Check your answers with an inverse calculation where possible. 1. The population of two towns is 265 846 and 486 720. How much less than 1 000 000 is this? 2. A survey found 234 690 people like peanut butter, 190 355 like jam and 321 100 people like cheese. How many people were interviewed in the survey? game, 3. During a rugby contest, 54 342 people watched the first while 49 990 people watched the second game. If 156 330 people watched all three games, how many watched the third game? What is the difference between nine thousand and the sum of 5 470 and 1 388? A farmer has 2 050 sheep, 1 475 pigs, 4 875 cattle and 478 horses. If his neighbour has 10 134 animals, how many more animals does the neighbour have? 6. The difference between two numbers is 350 578. If the first number is 405 322, what is the second number? 7.
