$\text{a) 10-12-8}$

$\text{= (-2) – 8}$

$\text{= (-2) + (-8)}$

$\text{= -10}$

$\text{b)4-(-15)-5+6}$

$\text{= 4 + 15 – 5 + 6}$

$\text{= 19 – 5 + 6}$

$\text{= 14 + 6}$

$\text{= 20}$

$\text{c)2-12-4-6}$

$\text{=(-10) – 4 – 6}$

$\text{=(-10) + ( -4 ) + ( -6 )}$

$\text{= (-14) + (-6)}$

$\text{= -20}$

$\text{d)-45-5-(-12)+8}$

$\text{=(-45)+(-5)+12+8}$

$\text{=(-50) + (12 + 18)}$

$\text{= (-50) + 20}$

$\text{= -30 }$

$\text{#bich2k9}$
