Using distributive property, find 80 × - 18 + - 2 × 80

To find 80 × - 18 + - 2 × 80 . Distributive property: For integers a , b , c , we have a × b + c = a × b + a × c 80 × - 18 + - 2 × 80 = 80 × - 18 + - 2 = 80 × - 20 = - 1600 Therefore, 80 × - 18 + - 2 × 80 = - 1600

Using distributive property, find 16875 × - 2 + - 16875 × 98

16875 × - 2 + - 16875 × 98 Distributive property: For integers a , b , c , we have a × b + c = a × b + a × c We have 16875 × - 2 + - 16875 × 98 = 16875 × - 2 + - 98 = 16875 × - 100 = - 1687500 Therefore, 16875 × - 2 + - 16875 × 98 = - 1687500

Using distributive property, find 12356 × 99 - - 12356

To find 12356 × 99 - - 12356 Distributive property: For integers a , b , c , we have a × b + c = a × b + a × c We have 12356 × 99 - - 12356 = 12356 × 99 + 12356 = 12356 × 99 + 1 = 12356 × 100 Therefore, 12356 × 99 - - 12356 = 1235600

Using distributive property, find 2354 × 657 - 354 × 657

To find 2354 × 657 - 354 × 657 . Distributive property: For integers a , b , c , we have a × b - c = a × b - a × c We have 2354 × 657 - 354 × 657 = 657 × 2354 - 354 = 657 × 2000 = 1314000 Therefore, 2354 × 657 - 354 × 657 = 1314000

Complete the given table. × - 2 - 3 4 - 5 - 2 3

To complete the given table. Integers: A collection of natural numbers, their negatives and zero. Zero is neither negative nor positive. While multiplying integers, multiply the digits and then use the rules to multiply the sign. + × + = + Example: + 13 × + 10 = + 130 - × - = + Example: - 20 × - 30 = + 600 + × - = - Example: + 13 × - 13 = - 169 - × + = - Example: - 30 × + 5 = - 150 Now we can write the missing integers the table as follows. × - 2 - 3 4 - 5 + 10 + 15 - 20 - 2 + 4 + 6 - 8 3 - 6 - 9 12 Thus, we completed the given table.
