Penyelesaian soal :

[tex] \it ( - 8) + 25 - (14 \times 5)[/tex]

[tex] \it = ( - 8) + 25 - 70[/tex]

[tex] \it = (( - 8) + 25 ) - 70[/tex]

[tex] \it =17 - 70[/tex]

[tex] \it = - 53[/tex]

___

[tex] \it ( - 7 \times 4) + (5 + 15)[/tex]

[tex] \it = ( - 28)+ (5 + 15)[/tex]

[tex] \it = ( - 28)+ 20[/tex]

[tex] \it = - 8[/tex]

____

[tex] \it \frac{3}{4}° [/tex]

[tex] \it = \frac{3}{4} \times 60 \: '[/tex]

[tex] \it = 0.75 \times 60 \: '[/tex]

[tex] \it = 45 \: '[/tex]

_______
(-8) + 25 - (14 × 5) =

= (-8) + 25 - (14 × 5)
= 17 - 70
= -53

(-7 × 4) + (5 + 15) =

= (-7 × 4) + (5 + 15)
= -28 + 20
= -8

¾° =

= ¾ × 60'
= (3 ÷ 4) × 60'
= 0,75 × 60'
= 45'
