Question

1.Comparati numerele: x=-15+ |-4| si y=-15×2-|4|


2.Se dau numerele:a=(-7)x(-12)-6x18
b=(-5)x17-4x(-12).
Calculati |a-b|

Answer 1

1. x= -15+|-4|= -15+4= -11

y= -15x2-|4|=-30-4= -34

x>y

2. a= (-7)x(-12)-6x18= -84-108= -192

b=( -5)x17-4x(-12)= -85-(-48)= -85+48=-37

|a-b|= |-192-(-37)|= |-192+37|= |-155|= 155
