8. Select each statement that is equivalent to the following expression.* 10 + (-2)
A. The temperature is 10 degrees and it falls by 2.5 degrees.
B. You buy one item for $10 and buy another item for $2.50.
C. Your elevation is 2.5 meters above sea level. As you hike further, your elevation
decreases 10 meters.
D. The temperature is -2.5 degrees and it increases by 10 degrees.
E. Your friend gives you $10 at lunch and then gives you $2.50 after school.
F. Your elevation is 2.5 meters below sea level. As you hike further, your elevation
increases 10 meters.

the largest number of the four options is 1.8 x 10-2

you have it in scientific notation.

1.80 x 10-6   = 0.00000180

1.80 x 10-4   = 0.000180 (bigger, or "less small", than the former one)

so

1.8 x 10-2       = 0.0180. as you see. the "less small", or the biggest one of them all.

as you have negative exponent, it means you are dividing 1.8 by 100 (i.e. moving the dot towards left, two times).

if you had positive exponent for the scientific notation, power of tenths, you would be multiplying times 100 (moving the dot towards right) as below:

1.8 x (10)2 = 180

so. if you have negative exponent in scientific notation, move the dot toward left. if it is positive, toward right as many times the exponent tells you.
