I need help for this question.

Order the variables from least to greatest.

p(35 x 90) / 67
i(94 + [ 51 / 3])
o( 3 x 93) - 2
L (217 x 5) / 7
r(99 / 21) + 98
f(5 x -89) / 2
O(31 x 3) x 4
a(-5 x -100) - 489
s(2143 x 6)
l(675 x 2) / 3

just get out your calculator and do the math!

Or you can type the expressions into google, and it will do the math.
For example,
94 + [ 51 / 3] = 94 + 17 = 111
surely this cannot be too much of a challenge?!?

oobleck...

*facepalm*

To order the variables from least to greatest, we need to evaluate the expressions for each variable and compare the results.

Let's calculate the value for each variable:

p(35 x 90) / 67:
p = (35 x 90) / 67
p ≈ 47.9104

i(94 + [ 51 / 3]):
i = 94 + (51 / 3)
i = 94 + 17
i = 111

o( 3 x 93) - 2:
o = (3 x 93) - 2
o = 279 - 2
o = 277

L (217 x 5) / 7:
L = (217 x 5) / 7
L ≈ 155

r(99 / 21) + 98:
r = (99 / 21) + 98
r = 4.7143 + 98
r ≈ 102.7143

f(5 x -89) / 2:
f = (5 x -89) / 2
f = -445 / 2
f ≈ -222.5

O(31 x 3) x 4:
O = (31 x 3) x 4
O = 93 x 4
O = 372

a(-5 x -100) - 489:
a = (-5 x -100) - 489
a = 500 - 489
a = 11

s(2143 x 6):
s = 2143 x 6
s = 12858

l(675 x 2) / 3:
l = (675 x 2) / 3
l = 1350 / 3
l = 450

Now, let's order the variables from least to greatest:

f ≈ -222.5

a = 11

p ≈ 47.9104

i = 111

l = 450

r ≈ 102.7143

O = 372

o = 277

s = 12858

L ≈ 155

Therefore, the variables in order from least to greatest are: f, a, p, i, l, r, O, o, s, L.
