a , 9,87 + 6,48 - 1,87
= ( 9,87 - 1,87 ) + 6,48
= 8 + 6,48
= 14,48
b , 5,46 - ( 2,5 - 1,04 )
= 5,46 - 2,5 + 1,04
= ( 5,46 + 1,04 ) - 2,5
= 6,5 - 2,5
= 4

( 23 + 47) + (11 + 49) = 50 + 50 = 100

23+47+11+49 = 70 + 60 = 130
4.7.11.25 = 4 . 25 . 7 . 11 = 100 x 77 = 7700
5.9.3.2 = 5 x 2 x 3 x 2 = 10 x 6 = 60

A = \(2000-\left\{46-\left[24+74.4\right]:15\right\}\)
A = \(2000-\left\{46-\left[24+296\right]:15\right\}\)
A = \(2000-\left\{46-320:15\right\}\)
A = \(2000-\left(46-\frac{64}{3}\right)\)
A = \(2000-\left(\frac{138}{3}-\frac{64}{3}\right)\)
A = \(2000-\frac{74}{3}\)
A = \(\frac{6000}{3}-\frac{74}{3}\)
A = \(\frac{5926}{3}\)
