Ken is playing a game. He has 4289 points. Then he scores another 355 points. Ken’s target is 6000 points. How many more points does Ken need to reach his target?
This is a two-step problem. First, we need to work out the total points that Ken already has. To find Ken’s total points, we need to add together 4289 and 355. Nine plus five is 14. Eight and five is 13, plus the one we exchanged makes 14. Two and three is five. And one more that we exchanged makes six. And there’s nothing to add to the four. So Ken has 4644 points already. And we know his target is 6000. How many points do we need to add to 4644 to reach 6000?
We know that 44 and 56 are a pair that makes 100. So if we add 56 to 4644, that will take us to the next hundred, 4700. We know that 700 and 300 are a pair that make 1000. So if we add 300 to 4700, that takes us to the next thousand, which is 5000. Then we just need to add one more thousand to 5000 to take us to 6000. So we added 1000, 300, and 56. Ken needs to get 1356 more points to reach his target of 6000.
First, we added together the number of points which Ken already has, 4644. Then we found the difference between 4644 and 6000, which is 1356.
