Only one answer, brother with more treble in his channel than the other brother? 5^2 + 4mod3 =26 ---

Can you expand on your equation,you will get more response. What does the “mod” in 4mod3 represent? I guess mod3 means base 3? ---

(5 + 6 + SQRT(4)) x 2 = 26 ---

mod means modulo. It means the remainder after the first number is divided by the second. 4mod3 is the remainder after dividing 4 by 3, e.g 1. ---

Sorry, but the answer is 42. It’s the answer to life, the universe, and everything. ---

I get 43,at least my TI 83 gets 43. ---

Yes, but what is the question? ---

How do you get an answer of 42 or 43. (5^2)+(4 mod 3) … 5 to the power of 2 is 25 and 4mod3 is 1 … add them together for an answer of 26. You could insert brackets to change the order so that the equation reads 5^(2+(4 mod 3)) … then the answer is 125. Are you sure that this is the answer to everything. I thought the answer was an engine that got 200 MPG and developed 600 HP. ---

I calculated (5+6+2)(2) and got 26 this time. The first time I did 4^2 instead of sqrt4. I don’t know how to work the “mod” problems. At what level is this “mod” concept put forth? I just finished Algebra 151 (next is pre-calcus) last semester and have not yet been introduced to the process. And yes what is the question? Really I have never heard of the “mod” concept,probably should have in 3rd grade. ---

I LOVE it when Ray says, “There’s only one answer.” And I found another ten: 24+5-3 23+5- the square root of 4 (Keyboard here doesn’t do everything I wish it did.) 52 divided by (square root of 4)base 3 5x3!-([square root of 4]+2) 23 base 5 x square root of 4 4!+(2 base 35) 4!+(2 base 53) 4x3!+(2 base 5) 4x(3 base five !)+2 (4 base 5)x3!+2 Any more? ---

(25+4-3)/1 = 26 probably and therefore, probably (25+4-3)\*1 = 26 and (25+4-3)^1 = 26 as well
