Question

18÷2×5-[144÷12of2 -{80÷8-(6 of 3-44÷11) +7}]

Answer 1

Answer:

$\small18 \div 2 \times 5 - [144 \div 12 \: of \: 2 - < 80 \div 8 - (6 \: of \: 3 - 44 \div 11) + 7 > ]$

$\small = 18 \div 2 \times 5 - [144 \div 12 \: of \: 2 - < 80 \div 8 - (18 - 44 \div 11) + 7 > ]$

$= 18 \div 2 \times 5 - [144 \div 12 \: of \: 2 - < 80 \div 8 - (18 - 4) + 7 > ]$

$= 18 \div 2 \times 5 - [144 \div 12 \: of \: 2 - < 80 \div 8 - 14 + 7 > ]$

$= 18 \div 2 \times 5 - [144 \div 12 \: of \: 2 - < 10 - 14 + 7 > ]$

$= 18 \div 2 \times 5 - [144 \div 12 \: of \: 2 - < 10 - 21 > ]$

$= 18 \div 2 \times 5 - [144 \div 12 \: of \: 2 + 11]$

$= 18 \div 2 \times 5 - [144 \div 24 + 11]$

$= 18 \div 2 \times 5 - [6 + 11]$

$= 18 \div 2 \times 5 - 17$

$= 9 \times 5 - 17$

$= 45 - 17$

$= 28$
