Sociala medier sjuder av \u00e4nnu ett “enkelt” matteproblem som skapar stor uppst\u00e5ndelse. Vid f\u00f6rsta anblicken ser det ut som grundskolearitmetik, men det \u00e4r utformat f\u00f6r att f\u00e5 \u00e4ven de smartaste vuxna att f\u00e4lla.<\/p>\n
Utmaningen? L\u00f6s $50 + 50 \u2013 25 g\u00e5nger 0 + 2 + $2 utan minir\u00e4knare.
\nVarf\u00f6r folk g\u00f6r fel
\nDe flesta som g\u00f6r fel g\u00f6r det f\u00f6r att de l\u00e4ser ekvationen fr\u00e5n v\u00e4nster till h\u00f6ger, som en mening. Om du r\u00e4knar p\u00e5 det h\u00e4r s\u00e4ttet kan du sluta med $0 eller $4, men i matematikens v\u00e4rld finns det vissa regler vi m\u00e5ste f\u00f6lja.
\nL\u00f6sning: Bem\u00e4stra PEMDAS\/BODMAS-f\u00e4rdigheter
\nF\u00f6r att hitta r\u00e4tt svar m\u00e5ste du anv\u00e4nda operationsordningen. Beroende p\u00e5 var du bor kan detta vara PEMDAS (parenteser, exponenter, multiplikation\/division, addition\/subtraktion) eller BODMAS.
\nRegeln anger att multiplikation m\u00e5ste g\u00f6ras f\u00f6re addition eller subtraktion.<\/p>\n
Steg-f\u00f6r-steg-uppdelning:<\/p>\n
Att k\u00e4nna igen multiplikation: Titta f\u00f6rst p\u00e5 mitten av ekvationen: 25 dollar g\u00e5nger 0 dollar. Allt multiplicerat med noll \u00e4r 0 dollar.<\/p>\n
Ekvationen ser nu ut s\u00e5 h\u00e4r: 50 dollar + 50 \u2013 0 + 2 + 2 dollar<\/p>\n
Addition och subtraktion: Nu kan du helt enkelt arbeta fr\u00e5n v\u00e4nster till h\u00f6ger.<\/p>\n
50 dollar + 50 = 100 dollar<\/p>\n
100 dollar \u2013 0 = 100 dollar<\/p>\n
100 dollar + 2 = 102 dollar<\/p>\n
102 dollar + 2 = 104 dollar<\/p>\n
Slutsvar: 104<\/p>\n
Varf\u00f6r spelar detta roll?<\/p>\n
Dessa pussel \u00e4r inte bara f\u00f6r skojs skull; de p\u00e5minner oss om hur l\u00e4tt det \u00e4r att gl\u00f6mma grundl\u00e4ggande regler snabbt. Det \u00e4r ett bra s\u00e4tt att h\u00e5lla hj\u00e4rnan skarp och se till att de gamla l\u00e4xorna inte gl\u00f6ms bort!<\/p>\n
