Question

Help me please!! Anyone??

Answer 1

14)(4^{2}+2) x 3 = 54
put the paranthesis around 4 squared and 2
15)a natural number is always a whole number, however, a whole number is not always a natural
16) 10, because natural numbers can only be positive, also, zero is not a natural number
17) 3, for abc/abc will equal 1, leaving 3 x 1 = 3
18) No, for if it is division or multiplication, it will have completely different results
19) (x times y) times z ;  x times (y times z)  ;    x times y times z

hope this helps :D
