This table shows the height of three mountains. Mount Everest, Mount Kilimanjaro, and Ben Nevis. How much higher is Mount Everest than the combined height of the other two mountains in metres?
To find out how much higher Mount Everest is than the other two mountains combined, first we need to add together the height of Mount Kilimanjaro and Ben Nevis. So we need to add 5895 and 1344. Five plus four is nine. Nine plus four is 13. Eight plus three is 11, plus the one we exchanged makes 12. Five plus one plus the one we exchanged make seven.
Now we can subtract the combined height of these two mountains from the height of Mount Everest. 8848 subtract 7239. In the ones column, we need to subtract nine from eight. As eight is smaller than nine, we can take a 10 from the tens column. And then we can subtract nine from 18, which is nine. Three take away three leaves us with nothing in the tens column. Eight take away two is six. And eight take away seven is one. Mount Everest is 1609 metres higher than the combined height of Mount Kilimanjaro and Ben Nevis.
