Solve:

1) -3 + (-1) * 2 =

 

2) -10 - 1 / 1 = 

 

3) -6 + (-4) / (-4) = 

 

4) (-6.3) - (-7.46) =

 

5) -7 * 6 * -8 = 

 

6) ½ * 1.3 =

Just remember, Gamemaster.......we perform multiplication/division from left to right - as we encounter them - before addition and subtraction

 

1) -3 + (-1) * 2 =  -3 + -2  = -5

 

2) -10 - 1 / 1 =   -10 - 1  =  -11

 

3) -6 + (-4) / (-4) =  -6 + 1    =  -5

 

4) (-6.3) - (-7.46) =   -6.3 + 7.46 = 1.16

 

5) -7 * 6 * -8 =  -42 * -8   =  336

 

6) ½ * 1.3 =   .5 * 1.3 =  0.65

 

6)   could also be worked as     1/2 * [1 + 3/10]  = 1/2 *13/10  = 13/20  

 

 

cool cool cool
