eight x two : four + ten - seven =8 x 2 : 4 + 10 - 7=16:4+10-7=4+10-7=14-7=7
eight x two : four + ten - seven = sixteen : four +ten - seven
= four + ten - seven = fourteen - seven = seven
nine + ƒive + seven + seven + ƒour + one + nine + one + one =
= 9 + 5 + 7 + 7 + 4 + 1 + 9 + 1 + 1
= 14 + 7 + 7 + 4 + 1 + 9 + 1 + 1
= 21 + 7 + 4 + 1 + 9 + 1 + 1
= 28 + 4 + 1 + 9 + 1 + 1
= 32 + 1 + 9 + 1 + 1
= 33 + 9 + 1 + 1
= 42 + 1 + 1
= 43 + 1
= 44
\(nine+five+seven+seven+four+one+nine+one+one\)
\(=fourty-four\)
8:4=2 (student)

1)60(sixty)
2)10(ten)+10(ten)+20(twenty)+10(ten)-2(two)=48(forty - eight)
=1+20+30+7+2=60(sixty)
