Answer 1

a)

$27.39 - 39.26 = - 11.87$

b)

$97 + 97.99 = 194.99$

c)

$37.63 + 37.24 - 87.35 = - 12.48$

d)

$32.34 - (34)2 \div 32 + 30 - 0.3 = 32.34 - 68 \div 32 + 30 - 0.3 = 32.34 - 2.125 + 30 + 0.3 = 60.515$

e)

$2 \div 42 + 39 \div 93 \div 33 = 0.08 + 0.41 \div 33 = 0.08 + 0.01 = 0.09$

f)

$2 - ((3 \div 52 - 23.18 \div 32 + 3.11) \div 27) + 6) = 2 - ((0.05 - 0.72 + 3.11) \div 27) + 6) = 2 - ((2.44 \div 27) + 6) = 2 - (0.09 + 6) = 2 - 6.09 = - 4.09$
