Question

8-8÷8+{8×8+[8×8-(8×8-a)÷8]×8}=527

Answer 1

$8-8\div8+\left\{8\times8+[8\times8-(8\times8-a)\div8]\times8\right\}=527$

$8 - 1 + \{ 64 + [64 - (64 - a) \div 8] \times 8 \} = 527$

$7 + \{64 + [64 - (64 - a) \div 8] \times 8 \} = 527$

$64 + [64 - (64 - a) \div 8] \times 8 = 527 - 7$

$64 + [64 - (64 - a) \div 8] \times 8 = 520 \: | \div 8$

$8 + 64 - (64 - a) \div 8 = 65$

$72 - (64 - a) \div 8 = 65 \: | \times 8$

$576 - 64 + a = 520$

$a = 520 - 576 + 64$

$a = - 56 + 64$

$a = 8$
