Step-by-step explanation:
(1) 20-(10-3+2) (2) 50-[20+{30-(20-5)}]
= 20-( 10-5) = 50-[20+{ 30-(15)}]
= 20-( 5 ) = 50-[20+{15}]
= 20-5 = 50-[35]
= 15 = 15
(3) 100-3[20+{50-40}] (4) 5+[6{5-4+1}]
= 100- 3[20+10] = 5+[6{ 5-5}]
= 100-3[30] = 5+[6{0}
= 100-90 = 10 = 5+[0] = 0
(5) 25×{(48÷4) -9}
= 25 ×{ 12 -9 }
= 25×{3} = 75
