Question

write an expression that has a value of 100 and follows these restrictions. (1) uses each of the four operations at most once. (2) uses no parentheses. (3) uses only the digit 3.

Answer 1

Answer:

1) uses each of the four operation at most once:

("at most" basically means either we have to use any 1 operation at a time or no operation must be used)

if 100 is to be written without any operation then 100=100.

if only addition is used then 100=51+49

if only subtraction is used then 100=121-21

if only multiplication is used then 100=50×2

if only division is used then $100=\dfrac{500}{5}.$

2) if we don't have to use any parentheses

then 100=55+45 or 100 could be expressed other ways as well.

3) uses only digit 3:

$100=33\times 3+\dfrac{3}{3}.$

Answer 2

33 * 3 + 3/3 = 100

I do not believe u have to use all of the operations because it says " at most once ".
