Answer 1

h. 60 + [(4 + 2) - 5]

 =  60 + [(6 - 5]

 = 60 + [1]

  = 61

i.150 - [(5 - 1) - (4 - 3)]

 150 - [(4 - 1)]

 150 -  [3]

 147

j. 250 + ((7-2) + (4 - 1) + (3 - 2)]

250 + ((5 + 3 + 2)]

250 + 10

260

k.  450 - {6 + [4-(3-1)]}

450 - {6 + [4-2)]}

450 - {6 + 2)]}

450 - 8

442

1.  520 + {8 - 3+ [9 - (4 + 2 - 1)]}

520 + { 5 + [9 - 5)]}

520 + { 5 + 4 ]}

520 + 9

529

m. (150 - 5) - {14 + (9- 6 + 3)}

( 145 ) - {14 + ( 3 + 3 )}

( 145 ) - {14 + 6 }

145  -  20

125

n. 500 - {6 + [(14 - 6) - (7-2) + (4 - 1)]}

500 - {6 + [(8 - 5 + 3)]}

500 - {6 + 6}

500 - 12

488

ñ. (30 - 20) = 2 + (6 x 5) = 3 + (40 - 25) = 9 -6                                                                                                        10 = 2 + 30 = 3 + 15 = 3

10 = 32 = 18 = 3

o. [(9 - 4) = 5 + (10 - 2) = 4] + 9 x 6 = 18 + 2

[5 = 5 + 8 = 4] + 54 = 20

[5 = 13 = 4] + 54 = 20

p. (9 + 3)5 - 2 = (3-2) + 8 x 6 = 4:2 + 5

(12) 5 - 2 = 1 + 8 x 6 = 2 + 5

60 - 2 = 49 = 7            

58 = 49 = 7 ​​
