五條數唔識!HELP

發問:

1. 9除(-3)-(-2)乘3=? 2. 45-(-3)(-3)(-3)=? 3. -45-(-4)(-4)(-4)(-4)=? 4. 12+(-12)=? 5. 15-(-4)=? HELP! HELP!HELP ME!

最佳解答:

要先乘除，後加減 1. 9÷(-3)-(-2)×3 =(-3)-(-6) =(-3)+6 [負負得正，所以變+6] = 3 2. 45-(-3)(-3)(-3) = 45-9(-3) = 45-(-27) = 45+27 = 72 3. -45-(-4)(-4)(-4)(-4) = -45-(16)(16) = -45-256 = -301 4. 12+(-12) = 12-12 = 0 5. 15-(-4) = 15+4 = 19
