Answer 1

${\huge{\red{\boxed{\green{\boxed{\blue{\boxed{\orange{\boxed{\pink{\boxed{\mathcal\purple{S∅LUTI∅N}}}}}}}}}}}}}$

100 - [70 - {50 - ( 30 - 15 - 7)}]

= 100 - [70 - {50 - ( 30 - 22)}]

= 100 - [70 - {50 - ( 8)}]

= 100 - [70 - {50 - 8 }]

= 100 - [70 - { 42 }]

= 100 - [70 - 42 ]

= 100 - [28]

= 100 - 28

= 73
