a)    36 : 4 x 5 + 12 – 4 =

 

b)    540 : 3 + 5  =

 

c)    120 : 6 +( 25 x 2) =



d)    (20 – 30 x 8) =



e)    10 + 24– (4 x 2)  =​

Answer 1

$a)(7 \times 7 + 5) \div 6 \\ (49 + 5) \div 6 \\ 54 \div 6 \\ \large \boxed{ \: \red{9} \: }$

______________________________________

$b)36 \div 4 \times 5 + 12 - 4 \\ 45 + 12 - 4 \\ 57 - 4 \\ \large \boxed{ \: \red{53} \: }$

______________________________________

$c)540 \div 3 + 15 \\ 180 + 5 \\ \large \boxed{ \: \red{185} \: }$

______________________________________

$d)120 \div 6 + (25 \times 2) \\ 20 + (25 \times 2) \\ 20 + 50 \\ \large \boxed{ \: \red{70} \: }$

______________________________________

$e)(20 - 30 \times 8) \\ 20 - 240 \\\large \boxed{ \: \red{ - 220} \: }$

______________________________________

$f)10 + 24 - (4 \times 2) \\ 10 + 24 - 8 \\ 34 - 8 \\ \large \boxed{ \: \red{26} \: }$
