Which is the smallest of the following 4 numbers? Can You Solve In Your Head? 

Being out of school for nearly 49 years and retired I like to refresh my poor math skills, keep up the good work!!

a) = 1, b) = 11, c) = 1, d) = 0

Remember sitting in math class... and hearing what you didn't understand... and NOT wanting to ask questions??? With this math class you can rewind as much as needed

In primary, we started with addition and subtraction. Order ? Always left to right. Then, the multiplication got introduced. Order ? Multiplications first, then, left to right. Add the division. Divisions = same priority as multiplication. At about the same time, the parentheses got introduced. Now, order become : Content of parentheses, then multiplication & divisions, then addition & subtraction. Always left to right for equal priority.

Although my math teacher was to the point, it was boring. I wish I had a teacher like you, the enthusiasm is making it nice to keep watching.

Greetings. The answer is obviously (d) because 4^2-2^4 is the same as (2^2)^2-2^4= 2^4-2^4=0. It does not appear that any of the other answers would have resulted into a negative number.

Thank you

Paper and pencil? There’s nothing here that should require even that. Both the figuring and remembering the answers should be a simple mental exercise.

Stupid me overcomplicating C forgetting there's no constant and trying to evaluate using binomial theorem (iykyk it gets very large very fast)

Does smallest include/mean "largest negative?"

d) 0 a = 1 = c b = 11

What you say about the number of times a number is multiplied by itself is misleading. Something squared is not multiplied twice, only once. 3^3 is really only two multiplications. Perhaps you can be more clear so people don't literally multiply the number of times of the exponent. The number of times to multiply is the exponent MINUS one.

Again, there is no reason for PEMDAS in this problem! PEMDAS does not apply. For example: (3-2)^5 = (1)^5 = (3-2)*(3-2)*(3-2)*(3-2)*(3-2) = 1 x 1 x 1 x 1 * 1 = 1 This is the only expression that you could possibly use your PEMDAS on of the four, and as you see, it doesn’t matter which you do first, what’s inside or expanding the exponent. If you can’t understand this then there is no way you can understand a parenthetical Statement of the form a(x + y)^b, where you have your choice where to Start, you can either expand the implied multiplier, or the exponent, but you actually cannot start inside the Parentheses because they are variables and the exponent and implied multiplier are constants. In mathematics we use letters like a, b, and c as constants and x, y, and z as variables; ax + by, + cz = 0 for example!. Implied multipliers are how many times you add the parentheses and the exponent is the number of times you multiply the parentheses and the other is carried along. For example 2(x + y)^3 = (x + y)^3 + (x + y)^3 = 2(x + y) * 2(x + y) * 2(x + y) = {(x + y) + (x + y)} * {(x + y) + (x + y)} * {(x + y) + (x + y)} Notice: your understanding of PEMDAS does not apply! The “P” in PEMDAS does not mean just what’s inside the parentheses, it means the parenthetical statement, HUGE DIFFERENCE! Implied operators only operate on the object they are associated with and cannot be separated or converted into a fixed operator, which would have a different meaning.

d. in about eight seconds in my head. Sorry it took so long. Allergy needs kicking in.

I think the answer is b , John

Simple and short explanations are more better than just to cover up the time of making video

got it 0 simple exponents 1 vs 11 vs 1 vs 0 thanks for the tun

Another cream puff. Thanks Boss.

d) 0

d) = 0

d. 16 - 16 = 0

C is a a remarquable Identity

D 16-16=0

d)

I may have screwed up my whole life, but I still dominate at math.

D)=0

1 1:12

Note about phone numbers: If you want "demonstration" numbers they are in the form: NXX-555-0XXX, where N is a digit from 2-9, and X is a digit from 0-9. This is well known, and you will see these numbers in movies and TV shows. It prevents poor unknown people from getting bombarded with useless phone calls. Hopefully people don't call the number you mentioned.

Oh I got it Sorry for the mistakes I did

Gotta be D, I get 0

D = 0

Answer is a

Shalom John

Probably d 16-16 is 0

D--0

1 a

Sorfy got it wrong
