Answer 2

53-a: 5+3-1 =7
b: 8-1-5=2
c: 15+5+10= 30
d: 16-2+1=15

54- a:
$9 + 5 \times 6 = 84$
b:
$21 \div 3 + 4 = 11$
c:
$30 - 6 \div 2 = 27$
d:
$40 - 5 \times 8 = 0$
e:
$6 \times 10 - 8 \div 2 = 30$
f:
$20 + \div 4 + 6 \times 8 = 53$
i:
$50 + 12 \div 2 = 56$
j:
$16 \div 2 + 6 = 14$
k:
$3 \times 7 - 2 \times 5 = 11$
l:
$5 \times 6 \div 3 - 8 = 2$
