Introduction: The ability of oral calculation is a basic ability in mathematics learning. The following are the oral math problems in the first volume of primary school mathematics provided by Bian Xiao. You can refer to the exercises. For more exercises, please pay attention to the new graduate examination network. 2+ 1= 9+6= 8+5= 3+8= 8+8= 12+3= 7+6= 7+8= 6+6= 3+9= 5+6= 5+8= 4+7= 8+4= 4+9= 6+8= 8+6 = 9-4= 3+6= 4+8= 8- 1 = 6-6= 5+6= 8+2= 2+9= 10-6= 5+3= 6+9= 654 38+06-6= 9+8= 3+4= 7+5= 10+4= 8+7= 9+9= 5+9= 7+7= 9+7= 19- 15= 1 3+5= 8+ 1= 15- 15= 13-2= 8+9= 3+ 1= 8+8= 1 1- 10= 7- 2= 6+()=9 ()+6= 1 5 2+5-6= 9-8+5= 4+4-8= 5+()= 10 2+( ) = 10 4+9-6= 10-8+2= 7+2-8= 8+ 1 0= 3+7= 4+7= 9-6= 7+4= 2+6= 8+9= 65438 +00-3= 8+7= 9+3= 8+ 1= 8-7= 5+8= 7+0= 9+5= 17- 10= 18-2= 10- 1 0= 19- 1 1= 5+2= 18- 1 1= 14+2= 17- 1 1= 18-6 = 16- 1 1= 15- 1 1= 17+2= 9-7= 9-2= 8+4= 14-4= 6+6= 1 0-8= 4+9= 5-0= 9+7= 6+4= 9-3= 5+4= 3+9= 3+5= 8+3= 8-3= 8+8= 6 5438+00+7= 14- 1 1= 17-6= 12- 1 1 = 4+( )= 14 3+() = 12 7-5+9= 13-8+4= 7+7-6= 1 1- 1 1= 8+7= 9+ 1= 1 1+ / kloc-0/= 16+ 1= 17+ 1= 12-3= 1 1-4= 7+4= 9+4= 1 2-6= 5+6= 6 5438+03-6= 7+6= 9+5= 9+3= 8+4= 17-8= 7-7= 5+5= 5+7= 12-3= 1 1-4= 16-7= 12-4= 1 0-8= 10+6= 7+4= 9+4= 7+5= 2+9= 3-2= 15-7= 17-7= 15-9= 16-6= 1 1-4= 9+6= 7+3= 1 0-5= 7+9= 6+5= 8+7= 7+5= 7+ 10= 0+7= 7+4= 9+5= 9+9= 12-4= 12-3= 1 1-6= 654 38+04-8= 13-6= 4+( )= / kloc-0/2 ()+6= 13 12-3+7= 1 1-3+6= 6+9-5= ( )+7= 15 ( )+5= 14 6+8-5= 6+8-8= 12-6+9=
