Jader solved the problem 854 – 279 below.
854-279=?
854-200=654
654-50=604
604-9=595
Jader is incorrect.
• Describe Jader's error.
• Explain how you would correct the error that Jader
made.
• Correctly solve 854 - 279.
Jader is wrong because she did not subtract all of the tens in 279. He should have subtracted 7 tens, not 5
tens.
The correct setup would look like:
Use the digits below to write a number with greatest possible value. Then write a number with the least possible value. Write each number in standard, expanded and word form.
5 9 8 6
Greatest:9,865
Expanded:9,000+800+60+5
word: nine thousand, eight hundred and sixty five
Least:5,689
Expanded:5,000+600+80+9
Word: five thousand, six hundred eighty-nine
