Solve the following table and explain what you understand about closure property of subtraction of whole numbers ?
First two rows are solved, try solving other rows too.
10 | - | 7 | = | 3 | It's a whole number | 24 | - | 74 | = | -50 | It's not a whole number but an integer | 15 | - | 10 | = | ?? | ?? | 35 | - | 75 | = | ?? | ?? | 80 | - | 100 | = | ?? | ?? | 97 | - | 23 | = | ?? | ?? | |
Explain closure property of subtraction of whole numbers by solving the following table:
189 | - | 156 | = | ?? | 476 | - | 989 | = | ?? | 67 | - | 543 | = | ?? | 8354 | - | 3298 | = | ?? | 88 | - | 99 | = | ?? | |
Whole numbers are not closed under subtraction. Explain how ? |
Demonstrate how subtraction of whole numbers does not always results in a whole number? |
