# Mental Math: Artillery Strike Sgt. Joe's Army

## 应用说明

Want to learn Mental Math & Defeat the Bad Guys at the same time? Use this App, it's a great way to become familiar with Mental Math.
This App includes training tools for Multiplication 1/10x, Squares Memorization 2/30, Cubes 2/30, and a Multiplication Marathon race 2/20 which consists of 438 problems, if you do not enable hints you can compete with others for a spot on the Leaderboard.
If you need a little help, you can enable hints, which will disable the Leaderboard for that game, but it will show you every math formula necessary in order to complete the problems using Mental Math. It is recommended that you study using the 1/10x Multiplication tool until you become very familiar using it. For every 2 problems that you can complete within 1 second, you will be awarded 2 "Bloodlust" Points at the end of the Marathon Race, Bloodlust Points, Correct Points, and the Seconds it took you to complete the race will all be calculated in your Final Score.

Explaining the Technique in this and other Mental Math Themes, Why is the App put together like it is? Combos, Bloodlust Explains
*****
Start with a good basic foundation, try this method, most people hate anything above 10x10 in multiplication even if they did graduate. Give this App a serious try, My Mental Math Games is great for learning multiplication 2/20 squares 2/30 cubes 2/30, and Memorization on how to come up with the answers rather quickly. I put a lot of thought into it while creating it and spent over 30 hours putting the App together. It works because I break larger problems into small groups, then add them together again.
In the Basic Theme you can do Combos by answering 2 problems within 1 second which teaches our brains how to do compartmentalization and makes it feel as tho it's normal after a few sessions Basically gets you used to storing the answer of a basic problem you know, while figuring out the next one, this helps prepare our brains for storing 1 set of numbers while calculating others for good mental math, (but it is basic, no sounds, nothing, just math.) in the Army Theme, the Combos are called Bloodlust Points, when you get 10 Bloodlust points, it unlocks Bloodlust Sgt. Quotes to Taunt the Enemy's Soldiers. You get problems correct you kill the enemies, you get problems incorrect, your soldiers get killed by the enemies. There is no time limit, but there is a second counter which will assist in calculating your final score. To make a High Score, (Correct Problems), (Bloodlust or Combo Points), (Seconds it took to complete the Marathon Race.) 2/20 multiplication, 2/30 Squares, and 2/30 Cubes. It starts out basic, gives someone a basic understanding of it, then it gets very difficult, and by the end of it, you'll absorb the concept of calculating over 20x20 double digits in your mind,
66x62=?
Change the 62 to 60 in our minds because it's closer to 60 than 66 is to 70.
6x6=36
6x6=36
In my mind I see, "36 36"
since the 2nd group has double digits, add the 2 middle characters together.
6+3=9
Then since we are dealing with multiplying multiple digits, we put them together and add a zero.
3960
(Now we ask ourselves, how many times did we go down? The answer is 2 from 62 to 60)
66x2=132
3960+132=
First add the hundred character mentally, it's easiest.
3960+100=4060
