MAT 101 TEST 1 Questions with Detailed Explanation

MAT 101 TEST 1

(2*3)4=2(three*four)
(ab)c= a(bc) - ANS-associative property for multiplication

(10-five)-3
IS NOT EQUAL TO
10-(five-three) - ANS-why is not there the associative assets for subtraction?

(a)(b) = (b)(a) - ANS-comunitive belongings for multiplication

(a+b)+c = a+(b+c) - ANS-associative assets for addition

*(20/4)/2* NOT EQUAL to *20/(4/2)* - ANS-why isn't there the associative belongings for
division?

2: number ends in an even variety
5: wide variety results in zero or 5
10: number ends in zero
4: 4 divides into closing 2 digits

12: 3 and 4 divide frivolously - ANS-divisibility rules
(2, five,10, 4, 8, 3, 9, 6, 12)

three*1 = 1*3
a*1 = 1*a - ANS-identity belongings for multiplication

6-3
IS NOT EQUAL TO
three-6 - ANS-why isn't always there the commutative assets for subtraction?

A(b-c) = ab-ac - ANS-distributive assets over subtraction

a(b+c) = ab+ac - ANS-distributive property over addition

a/four
IS NOT EQUAL TO
four/a - ANS-why is not there a commutative belongings for division?
