Ihave to evalaute expressions can someone tell me which whay is the correct way.
15+ 20 ÷ 5
Is
15 + 4= 19 or 5 ÷ 5=9
210-5 x 30
Is it
210-150=60 or 205 x30=61590
Have you heard of BEDMAS?
it shows the correct order of operation in arithmetic
B-brackets first
E-exponents
D
M ...Division and Multiplication in the order they come
A
S ... Addition and Subraction in the order they come
so for your first one it is
15 + (20 ÷ 5)
=15 + 4
=19
thanks I got the next one
210-150=60
That's correct! For the second expression, you apply the order of operations according to BEDMAS.
210 - 5 × 30 becomes:
= 210 - (5 × 30)
= 210 - 150
= 60
So the answer is indeed 60. Well done!
