Add th hundrd first t gt: 1 + 2 = 3
Thn add th tens: 3 + 1 = 4
And dd th n' t get: 2 + 4 = 6
Nw, join th numbr tgthr to gt: 346
How is tht?
Think u can now add 2 numbers tgthr in ur hd?
Tr it: 23 + 12, 312 + 481, 1324 + 8635.
D not underestimate th wr of 'bit iz know hw'.
So, lrning to d mental arithmetic is ll but knowing hw t d it in t u n mng!
Mntl mth can b lrnd b nn with a bit f rti. For anyone tht h vr struggled with th basics of mthmti, mntl mth n allow u t not only mtr those bi but t perform them bttr thn th vrg person.
Thr r fundamental trik for each brnh of mth including multilitin, diviin, addition, nd ubtrtin. These tricks don't ruir n mmriztin, il aptitude r hours of tuding. On u know each trik you nl nd t rti thm fw tim to realize tht th wrk fr ll numbers, big or mll.
The bnfit f hving mntl mth a skill r extensive nd pervasive. All rnr f life ntin t least m numbers nd with th numbers invitbl comes math.
In our mdrn world we're ud to uing machines to hl u: lultr, computers, cash rgitr, t. Mntl math gives

Mental Mth Games
Th ttitud nd rh to the teaching f mental mth in hl has hngd rdill over th t four decades as a rult f th widrd u of calculators. Intrdud initill in th 1970s th optimistically named pocket lultr, ltrni lultr hv hrunk so tht they r nw truly pocket-sized and rtbl.
In dditin, calculators r rutinl inrrtd int thr dvi from mbil hn and computers t rulr and hing rt.
In thi brv nw world, kids wuldn't have t be tught mental mth, r lng diviin, r lulu, bu lultr uld mlt all computational tasks faster and more accurately than the human brin.
Calculators are indd uik, urt and lmt ubiquitous, yet w ntinu t nw tri where major ditr r attributed t milultin. In lmt ll f these , it i nt th muttinl dvi, b it calculator or mutr, whih h failed t compute th correct nwr.
Intd, the rblm is ttributbl t rtr rrr, so tht the person mking th calculation h ithr inrrtl inut wrong data or has misunderstood the mth undrling th lultin and rivd th right answer to th wrng utin.
The rlit is tht the lultr dn't rl nn frm th nd t have ntil math kill, bu t use a calculator ruir n undrtnding of the undrling mth rinil f th calculation.
In dditin, it uld b rgud tht mental mth kill are ruird tht a quick mntl lultin n be made t hk whthr the calculator's nwr i within th rng xtd.
