V\u00fdzva prijat\u00e1! Tieto internetov\u00e9 h\u00e1danky, ktor\u00e9 vyzeraj\u00fa tak jednoducho, ale o ktor\u00fdch sa polovica \u013eud\u00ed v koment\u00e1roch h\u00e1da, s\u00fa klasika.<\/p>\n\n\n\n
Z\u00e1merne, pre pr\u00edpad, \u017ee by som narazil na pr\u00edklad, ktor\u00fd m\u00e1te na mysli. Zvy\u010dajne ide o poradie oper\u00e1ci\u00ed (n\u00e1sobenie a delenie pred s\u010d\u00edtan\u00edm a od\u010d\u00edtan\u00edm).<\/p>\n\n\n\n
Tu je pre v\u00e1s mal\u00fd trik:<\/p>\n\n\n\n
7 + 7 \u00d7 7 + 7 \u00d7 7 \u2013 7 = ?<\/p>\n\n\n\n
Tu je postup, ako to urobi\u0165 (bez kalkula\u010dky a s chladnou hlavou): N\u00e1sobenie a delenie maj\u00fa prednos\u0165: Najprv vyrie\u0161ime tieto dve oper\u00e1cie v strede.<\/p>\n\n\n\n
$7 \\div 7 = \\mathbf{1}$
$7 \\times 7 = \\mathbf{49}$ Teraz spoj\u00edme v\u00fdsledky: Zap\u00ed\u0161eme ich sp\u00e4\u0165 do riadku.<\/p>\n\n\n\n
7 + 1 + 49 \u2013 7
S\u010d\u00edtanie a od\u010d\u00edtanie z\u013eava doprava:<\/p>\n\n\n\n
7 + 1 = 8<\/p>\n\n\n\n
8 + 49 = 57<\/p>\n\n\n\n
57 \u2013 7 = 50
V\u00fdsledok je 50.<\/p>\n\n\n\n
Kde rob\u00ed v\u00e4\u010d\u0161ina \u013eud\u00ed chyby?<\/p>\n\n\n\n
\u010casto jednoducho po\u010d\u00edtaj\u00fa z\u013eava doprava, ako najlep\u0161ie vedia (7 + 7 = 14, potom 14 \u00f7 7 = 2 at\u010f.), \u010do je najr\u00fdchlej\u0161\u00ed sp\u00f4sob, ako z\u00edska\u0165 jednotku z matematiky.<\/p>\n\n\n\n
Mysleli ste pr\u00edklad ako tento, alebo in\u00fd trik s ovoc\u00edm alebo top\u00e1nkami, ktor\u00fdch hodnota sa v ka\u017edom riadku men\u00ed?<\/p>\n","protected":false},"excerpt":{"rendered":"
