Question

a) 49 - 32 + 16 

b) 36:6.3

c) 36 -18 : 2.3 +8

d) 11² -6²  .3  

Answer 1

a)
49-32+16
=17+16 =33
b) 
36: 6 .3 
=6.3 =18
c)
36 -18 :2.3+8
= 36-9.3+8
= 36-27+8
= 9+8 = 17 

d) 

11^{2 -} 6².3  = 121 - 36 .3 = 121 - 108 = 13

 

Answer 2

\(a,=17+16=33\)

\(b,6.3=18\)

\(c,36-18:6+8=36-3+8=33+8=41\)

\(d,=121-108=13\)

Answer 3

`a)`

`49 - 32 + 16 `

`= 17 + 16`

`= 33`

 

`b)`

`36:6.3`

` = 6 . 3`

` = 18`

 

`c)`

`36 -18 : 2.3 +8`

` = 36 - 18 : 6 + 8`

` = 36 - 3 + 8`

` = 33 + 8`

` = 41`

 

`d)`

` 11^2 - 6^2 . 3`

` = 121 - 36 . 3`

` = 121 - 108`

` = 13`
