Show how 10 - 4 helps you solve 30 - 4.We know 10 - 6 = 4.Furthermore, we can take out 10 from 30 and subtract 6 from 10.[tex]\boxed{ \ 10 - 4 = 6 \ }[/tex]Then we can add what is left, which is 20 to add to 6.20 + 6 = 26So, results from 30 - 4 are 26.Let's review the steps again.[tex]\boxed{ \ 10 - 4 = 6 \ }[/tex][tex]\boxed{ \ 20 + 6 = 26 \ }[/tex][tex]\boxed{ \ \boxed{ 30 - 4 = 26} \ }[/tex]Learn more4 times as much as 3 is ... ten thousands divided by ten ²/₇m - ¹/₇ = ³/₁₄ solve step by step : show how, 10 - 4, helps you, solve, 30 - 4, subtracts, add, waht is left, the common core mathematics curriculum
